Look at the Marylebone area on the map, press R3 up to zoom in, there is a small half circle road under the word Marylebone that connects to a road that goes east to west. You can not enter this road because buildings are in the way. Go to the very last road next to the M in Marylebone and head south to half circle road, go into the south part of the half circle road and you will see the save garage gate open. You can save one car and bike here.
Look at the map on the far east (left) side, there are 2 roads next to each other that goes north to south. Go up (north) to the last road at the top of the map and head east to these 2 roads, just before you get to the intersection of the 1st road on the right there is short 3rd road. You will see an orange, green and grey drag racer also known as a funny car. It is longer than the other cars and the back tires are big.
Look at map for the shoreditch area,push R3 up to zoom in,now the road next to S in shoreditch:go up(north) 2 blocks, now go west,to make sure you are on the correct road you will drive under a bridge. It's in the middle of the block on your right next to some garbage dumpers. Secret car: on this same block keep going west to the next block and you will see a formula 1 racer with logo that says: sing star party, it's a blue,grey and blue green color. If you unlocked eddie during free roam, he's closer to the garage and car.
At the starting point when using mitch, turn right into the alley now turn left you will see a grey convertable. It only appears when you are using mitch during free roam. Save garage:at the starting point when using mitch,drive in the direction you are facing look to your left and you will see a gate in a alley open up. This is the save garage, you can save one car and one bike here. It's a few feet from the starting point if you are using mitch.
When you play as Sam on free roam and you start in the car drive forward till you're on the main road turn left then turn left again at the traffic lights and go straight you will see a car there and it's not wide and has a UK flag on it.
Come out of the art gallery and turn left and go right round to the end of that road and turn left keep going down that road till you come to a load of trees and slow down and keep looking right you will see a motorhome it is not worth steeling you can't see where you are going
Also don't steel a single decker or double decker bus as they are just as bad but what you can have fun with I did it the other day was head to south london and you should see a dust lorry they are not good for getaway vechiles but great fun for banging into other cars
Now if you want a quick getaway look for a subaru imprezia in my opnion they are the fastest saloon on the road I think they do around 180mph
2 race cars & a pedal Bike on free roam (Jamahl) garage (anyone)
When you are on free roam with JAMAHL from where you start go out of the car park and turn right then a tiny way up the road on the right you will see some stairs which go up to a building then walk around the building and you will find a pedal bike. A little further up the road on your right you will see a garage will you can store cars in with any person so you can go back any time and get them out.
A little furter up on the left you will see somemore stairs if you go up them and walk around the building you will find a green sports car which you can also find in a race car painted way next to buckingham palace on a patch of grass it is white with stripes on but this other car is better then the last one and if you go straight up the road you will see a fence where most of the wood is hanging off.
Just drive straight at the part where the wood is hanging off and you will go over a jump if you drive a little way forward from the jump you will go into a square where you have to go back over the jump to get out look on the right and you will find a racing car which is quite fast.
