I've had this problem for a long time and have e-mailed the devs, so I would like to know if someone else has the same problem and if there's a way to solve it. The problem is that items that I get from crates and some that I buy, can't be sold; when I press the sell button nothing happens. I also have a problem with putting pieces because sometimes they don't appear as put (but the car gets its stats changed), it's only that the piece doesn't have the name of the car which is applied to. Thanks for reading!

Which is the fastest AWD car in the game? I guess is the Nissan Skyline, the Audi Quattro or the Audi R8 but I would like to know it. I'm refering to a car with all the maxed pieces (with or without engine swaps). It would be very cool if you also put your tuning set ups for the car (gearbox). Thanks!
