It's sonething I've thought of doing for a while and after driving kangoosports white stripped out 172 that he's just bought has swayed me. Only drove it for like ten mins or so, it was noisy, rattled, noisy, rattled some more, but I loved it. Don't get me wrong after I got back in mine it felt nice, but the smile per mile on that white one was awesome. People who don't see the appeal need to drive one. As a comparison to the cup, no idea mate. Buy it, enjoy it, sell it. After next week after the trackday I'm pretty sure mine will be either up for sale or sold in bits lol
