None of the race cars can be resold, period. The only one I've sold was the Falken Skyline and it technically doesn't count as a "race car." But the Minolta, the Lexus IS 200 Race Car...not even the RM cars car be resold. I think that would be so no one can do the "race this event to get this car and sell it" thing. Another thing that supports this theory is that the Bugatti Veyron nor the Mazda Furai are sellable, and they're pretty easy to obtain and both would be worth around 500K-1,000,000cr each. I mean, you do the PD cup 20 times and you've reached the cap. And that series is REALLY easy to beat. I don't think there's any car that has a resale value of over 200k.
