I had one forsale at 200k with buy it now price of 10mill.. some random bought it out I'm guessing it was a once off charitable kinda thing.. I'm not keen to tempt fait by buying and selling one as I'll get stuck with it.
Took me forever to sell mine when it finally did for minimum bid I won another one on a wheelspin the next day so I just free upgraded it to use it for the blizzard mountain Goliath it's a credits boost car tune it up and use it for mining cr from Goliath races you'll make more from one race than you would selling it
On a real note, they are one of the easiest he to obtain at (200k) and sell for max buyout of 11million if you have a rare car for sale, but aren’t a legend painter, yet still want to get a chunk of cash!
