As small a group as McLaren owners are vs Porsche, Ferrari, etc... there's no need to be bashing on each other. I've also got a 570GT. What I really wanted was a 600LT spider, but after showing the wife she was decidedly against a car with a bare carbon floor... and to be honest, with zero time to track a car, that car didn't make the most sense for a fun car when I'd rather be able to carry on a conversation in a normal tone of voice while driving.
I've never been a fan of the front end of the 720S, I think the 570 looks much better. The 720S wasn't out of reach for me or I suspect a lot of 570 owners. With some downpipes and a tune I expect to hold my own vs a 720, so I'll get what I feel is the best of both worlds. I may even get a 600LT body kit eventually sans the exhaust, and I'll have my own unique car.
This board doesn't see much action compared to other car forums I used to frequent. I appreciate invisiblewave's posts, he's helped put me in touch with some other forum members when I had questions, as well as give advice when searching for a reputable mechanic in my area. The forum could use more posters like that, our owner knowledge base is far below what you'll find on a Porsche forum, and for those of us who occasionally DIY when time permits, the more knowledgeable posters we have on this site the better.
