I used to kind of think like OP until I drove a Panamera 4S, it really sparked something, first time I got that similar to sex feeling while driving, changed my whole perception about cars. Also working valet few years ago helped a lot even if I only got to drive cars about 400 yards at most I drove just about everything out there and that really helped my perspective of cars, never judge a car until you drive it.
As for the Ferrari comments: I had the opportunity to take a gallardo LP-560 for a spin and no numbers or words could describe that experience and the way it made me feel (I was shaking when I got out of the car lol) point is: super cars are in a different league than other cars and yes I would pay >$200K for one.
O.P: i suggest checking out
www.relayrides.com to see if anyone has a 911(or any outher car you are interested in) for rent in your area and rent it for a day or weekend, I rented a 996 carerra for my bday weekend for 280$ and had the time of my life!!
