Judd,

You can do the entire in car in Opti-Coat 2.0. I did my wife's explorer. It is a permanent coating. It's very good for a long-term solution, but is not as good as many other options. I really like Sonax Polymer Net Shield. It beads water better and looks better, but only lasts about 8 months.

I think the new Cayman is pretty awesome. I'm not a Corvette guy. The RS5 will handle like a pig, but will look sweet. I think other than the 911, the M4 will be the best all around car.

I really like Sport Chrono for the auto rev match feature on my 7MT. I use it every time I drive. I would say it's less useful with PDK.
