Do not waste money on your car(s)'(s) looks only the performance. Customize your Crews cars both performance and visual because it's free. (View car then A to customize.) I chose muscle class then won the Dodge Charger R/T, then sold the muscle (better to get Pink Slip to the R/T because Racing tier 2 N02.) Then beat all (sell pink slip cars) buy the Lamborgini Murcielagio (spelling) then fully customize. Time saver do all performance races first and check to see if you unlock anything. This all worked for me hope it does for you too.
