I like my car themed pins, have a Bally Corvette, Stern Grand Prix & Checkpoint. A Nitro Ground Shaker has insane artwork, one of the best car themed backglasses from that era imo.
My advice would be to go play as many car themed pins as you can in next few weeks, save some more coin then make a decison. The Nitro Ground Shaker sounds good as well, half the fun is the chase in finding the game, best of luck.
