Some people like wine; some people like hard liquor. Eventually, you'll get drunk. The Porsche 911S will get you in illegal speeds without the drama of tires burning and fishtailing all over the place. It will make you look like a better driver. On the other hand, a Corvette ZO6 will do all the above. It may not have the sporty feel and more quality materials in the interior, but you'll have more money left over. Porsche has a way of making you feel special and feeling better that you just plunked down a load of cash. Luckily, I have both cars.
The 911 is one of the few cars you can drive comfortably to work everyday, take to the track on weekends in stock form, AND safely transport a child who is too small to ride in the front seat. This car turned out to be better than I expected, and I expected a lot. I want to drive it all the time because it is both very comfortable and very capable. But to really enjoy it, you need to take it to a safe, legal racing environment. I recommend AutoX events, PCA DEs or SCCA PDX events. Another surprising aspect I enjoy about the car is actually doing the maintenance. Flat 6 in a rear engine layout makes for a difficult car to work on, but the car is not that bad if you have some mechanical skills. After investing in some extra tools, I have been able to do all the basic maintenance, saving myself a ton of money and enjoyed learning about the car. However, if you have doubts, take it to a Porsche mechanic. The car handles interestingly. The weight bias is largely in the rear, and thus why the rear tires are so much wider than the fronts. So, expect the rear tires to do a LOT of the work accelerating, turning and braking. The front is relatively light and sort of just points the car for the rear to follow. Leaving PSM on should take away most oversteer fears you would expect with a RWD, rear engine car. It works well, and is not intrusive. Stock, the car accelerates and brakes great. It has pretty good lateral grip as well, however I think it is a bit slow on transitions because of stock spring rates. To fix this would subtract from the everyday road comfort. My car has the PDK and it is very nice, especially after I added the paddle shifter steering wheel. It is very fast upshifting and downshifting, and unless you absolutely must row your own gears, I recommend the PDK.
There's no other car like a 911. The best sports car for the money.
