I do almost a hundred miles a day (~92 miles if I go directly to work and directly home) and it's a dream. I have the magnetic ride option, so I can make the suspension so stiff that it can bend rims on pot holes, or so soft that it feels smoother than my wife's Malibu. I also have the active exhaust option, so it can sound mean, or you can make it so you barely even hear the exhaust inside the car aside from hard acceleration.
The power lets me make lane changes safely when needed. Ok, that's just what I tell myself. The power actually lets me pass tanker trucks or LINES of cars in short passing zones on my 2 lane, hilly, curvy, 55 mph commute. The sound system is great. The ride is however you want it to be. The seats are comfortable. I literally do not have a complaint, especially in comparison to the C6. The C7 interior is just such a nice place to be. On top of that, I've been averaging 24+ miles per gallon including hard pulls. I got the manual (my first one), so I'm rarely if ever in Eco mode (auto is always in Eco unless you're in paddle shift mode). The autos routinely put up 26+ mpg and either transmission can hit 30+ if you have a flat highway commute.
I picked it up for $27k off MSRP with only 2,227 miles on it. That was in August. Prices are even lower in the winter months if you're considering used. I really wanted the Grand Sport (base engine, wide body), but when I started looking at the amazing used deals, I just couldn't justify buying a new one for ~$20k more than I paid.
I've only had the Stingray for a few months, but I just got out of a C6 Corvette that I did the same commute in. On the C6, I literally changed hood struts when I first got it and both ends of the shift selector when nylon bushings failed (literally $8, a screwdriver and pliers, and an hour each, including searching CorvetteForum for what I needed to do). Otherwise, the only other things I had to do maintenance-wise were tires, air filter, and oil over 60k miles. Tires can be a little pricey, but I think they would be about the same on the P-car.
The Cayman is a sweet car, too. Definitely my favorite Porsche in the looks department with the slightly longer body (well, ignoring the 918 WAYYYYY out of my price range). The Vette will probably be cheaper maintenance wise in the long run, though, and probably easier to work on. And it's faster. ;-)
I am a wealth of Corvette knowledge (mostly useless) because I was reading about this car before it even came out. If you have any questions, feel free to ask.
.......well, that turned into an essay. Sorry about that.
