I have a few cars in my garage that locked. I'm not sure why. The one specifically in question is a Ferrari 250. It is the car that is 10 million credits. I purchased the car with tokens. I added some parts, a quick paint job and I am unable sell it on the auction house. The message is that the car is locked and cannot be sold. I am able to use the sell feature from the garage, but it will only pay 100 credits; similar to cars that are won while playing career mode. Does any know what constitutes a locked car?
