The following Frequently Asked Questions and Answers cover a lot of territory, and should be very useful to you!
Q01: How much will a Unicorn cost me at the Auction House? / Is buying a Unicorn from the Auction House the only way to get this Achievement?
A01: The average price should run between 5 million and 10 million or thereabouts once Turn 10 has brought the ban-hammer down on the cheaters who are using the money bug to boost their income. Bear in mind that the Unicorns that go up on the AH are put there by Turn 10 -- players cannot auction off Unicorns. You can also obtain one of them (and the Achievement) by attending one of the special events in which they are gifted online.
You can also get this when you import your Forza 3 save, assuming you either have one in it or you have the VIP DLC. If you have already started your game, you can move your save files onto a USB drive, make sure you have a Unicorn available on Forza 3 and then start a new game. Once the Achievement pops you can restore your old save file and you are good to go!
Q02: Which cars are considered to be Unicorn Cars?
A02: The following cars are known to be Unicorn Cars:
1969 Chevrolet Camaro SS Coupe
1993 MINE'S R32 Skyline GT-R

Q03: Why do I have to own Kinect to play Forza 4? / Do I have to own Kinect to play Forza 4?
A03: You do not have to have Kinect! In fact other than one Achievement worth only 5 GS the motion controller has no other mandatory application in the game. However if you DO own it, it is good to use since you can fully control the game with it, or you can drive with the standard controller and use the Kinect-based head-tracking feature to be able to look around while driving...
Q04: Why are there no Porsches?! / Where are the Porsches??
A04: The simple reason for this is that Porsche licensed out its brand and cars to Electronic Arts exclusively -- and while other companies including Turn 10 have the same deal with other car makers, EA is unwilling to allow the Porsche to be used in games other than its own.
Q05: Can I import my Forza 3 save into the game more than once/again? / I said "No" when it asked me if I wanted to import my Forza 3 file into the game - how do I do that now?
A05: You cannot. Put simply, you are given one and only one opportunity to import the file -- this takes place immediately after the very first race you drive in BEFORE you start Career Mode. If you say no, or you do not have a Forza 3 file to import at that point, that is all she wrote. To do it now, you will have to erase your current save and start over.
If you move your save off the console onto a USB drive and then delete it on the console, you CAN then import the Forza 3 save and you will unlock the Achievement, but if you move your old save back onto the console you will NOT find the gift cars there when you play again. Keep that in mind.
Q06: Some of the cars cost major credits! How do I earn lots of credits fast?
A06: Fast or really fast? Seriously, when you race through Career Mode the purses you win combined with the bonus money you get for Affinity and your Driver Level will add up fast, but if it is not fast enough, you can use the Money Grinding Tactic that is outlined in the Career Mode Section of the guide above.
Using the Grind Method -- which until we are told otherwise is not considered an exploit -- you can average between 300,000 credits and 500,000 credits an hour (depending on your Affinity and Driver Levels).
Q07: Do I have to have a Gold Account to play the Rivals Mode and use the Shops?
A07: Yes -- and No... Yes, you need a Gold Account to do the Online Rival Mode races and to use the shops, but you can do the Offline (Career Mode) Rival races with just a Silver Account.
Q08: Can I hire a driver in Forza 4 like we could in 3?
A08: Yes, but as with Forza 3 the driver takes half the purse, and you do NOT get XP or Affinity when you hire a driver, which is something to consider. But when you take into account the fact that Turn 10 did not include ANY of the endurance races in Forza 4, unless you flat-out hate a track or race in a series, there is no reason to hire a driver.
Q09: Does Forza 4 have Avatar Awards?
A09: It sure does! Two in total -- A Hat and a T-Shirt (the T-Shirt includes a Male and Female verison).
Q10: When I checked Autovista there were only a small number of cars there! How do I get more cars?
A10: For now you don't -- there are only base 23 cars available for use in Autovista plus 2 hidden bonus cars, the Warthog from Halo and Jay Leno's 1931 Bentley 8 Liter Sedan, but to get those you have to unlock the other cars. In addition to the base 25 cars that come with the game, cars will be added via DLC - at launch there is 1 DLC car available that adds itself to Autovista when you install it, and that is the 2012 BMW M5.
Q11: How does Affinity work? / What do I get for Affinity?
A11: The first four levels of Affinity gain you discounts on parts for that manufacturer and, once you reach the fifth level you start to get an increasing amount of bonus credits from them as your reward. The bonus credits increase every five levels. The discount levels are:
Level 1 -- 25% discount
Level 2 -- 50% discount
Level 3 -- 75% discount
Level 4 -- 100% discount
The discounts are only applied to Engine and Power, Platform and Handling, Drivetrain, Tire Compound, and Tire Width upgrades, and do NOT apply to Rim Style or Size, Aero or Appearance, or Conversion upgrades.
Q12: I see that I can buy Car Tokens that I can then use to buy the really expensive cars! Is that a better way to go than grinding for the credits?
A12: That is entirely your call -- but before you go the Token route, be aware of a few restrictions that are placed on cars purchased with Tokens: the first is that the car can NOT be sold in the Auction House. The second, if can NOT be gifted.
You should also be aware that the Tokens are not a 1-to-1 trace; in other words 1 Token does not necessarily equal 1 car, because the amount depends on the cost of the car. An expensive car can cost you up to 3 Tokens. For example to get all of the cars for the five most expensive cars Achievement will require you to spend 12 Tokens in total.
Q13: I was a VIP in Forza 3 but when I transferred my save into Forza 4 I am not -- how do I get that fixed?
A13: You don't. Your VIP Status from Forza 3 does NOT transfer into Forza 4. To have it in 4 you would have needed to puchase the Limited Edition version of the game. But don't worry, there will likely be a DLC added eventually just like in 3 to gain VIP status in the game.
Q14: Why is the game so easy? / Why are the AI racers so easy?
A14: The simple answer is it is not. Not really... You see the AI racers level is directly associated with your skill level, so the better you get at the game, the more competition they will provide. Conversely the more you crash into them, the more they are likely to do it to you. And just like in 3, you can make enemies among the AI drivers if you piss them off. I am just saying...
Q15: I got a warning saying my save file is corrupt! It is telling me to delete it?! What should I do?
A15: This is a known issue, it is being fixed, expect a patch soon. But in the meantime DO NOT delete your main game save or you will have to start over!!!
Turn 10 issued the following official instructions on the Forza 4 boards:
It has recently come to our attention that some of you may be receiving a corrupt save message when trying to save a file. This could happen with tunes, replays, paints or photos. While we are working on this issue please follow the steps below.
The Message: Your save file is corrupt. Please delete it from the Xbox Dashboard and create a new one.
If you receive the message above when trying to save a file please follow these directions:
(1) Go to the Xbox Dashboard.
(2) Move to My Xbox then scroll to the right and select “System Settings”.
(3) From inside System Settings select “Memory” then select the location where your game saves are located (for most people this will be on the hard drive).
(4) Scroll down the list until you find Forza Motorsport 4.
(5) From inside the Forza Motorsport 4 memory saves, you want to select the file that was corrupted. In most cases the file you are looking for will say “Corrupted” and have “!” next to it.
NOTE: PLEASE DO NOT DELETE your Game Save, If you do, you will lose all your game progress. Here is a list of the naming structure of your Forza Motorsport 4 saves:
(Your Gamertag) Saved Game – DO NOT DELETE THIS FILE. This is your main game save file and should only be deleted as a last resort.
(Your Gamertag) Car Setup Files Saved Game - These are your Tune Files.
(Your Gamertag ) PHOTOS Saved Game – This is all of your saved photos.
(Your Gamertag) LAYER GROUPS Saved Game – These are all of your created and purchased layer group files.
(Your Gamertag) Design Catalog Saved Game – These are all of your created and purchased car designs.
(Your Gamertag) Replays Saved Game – This save contains all our your saved replay info.
(Your Gamertag) WMV MOVIES Saved Game – This save contains all our your saved movies.
GHOSTS Saved Game – This is where your best time ghost files are saved locally.
(Your Gamertag) Game Options Saved Game – These are your saved game options.
Q16: How does the Car Club work? / How do I join a Car Club?
A16: The Car Club is Forza 4's version of guilds basically -- you can create one, or be invited to join one. To get invited you need to be on the Friend List of one of the officers or perhaps members - this last is unclear at the moment. They will see you on their list and can invite you.
Once you are a member of a Car Club you can borrow any shared cars from the Club, race against your mates, and challenge their times in Rival Races. This is largely viewed as a good addition to the game, since it creates a regular pool of mates to race against, allowing you to avoid the bumper-car and smash-up derby that largely is found in playing pick-up races.
Q17: What is the best way to unlock the Speed Demon Achievement?
A17: The easiest way to unlock this Achievement found so far is to go from the Main Menu > Free Play > Quick Race, and then select a fast car like the Bugatti Veyron 16.4.
Select the Le Mans Old Mulsanne Circuit and simply race it. When you hit the straight-away floor it and you should unlock it. Alternatively you can also unlock in on one of the long oval circuits in the Test Track.
