Here are some sports cars that I've driven and my impressions of them. I have a 2000 Boxster S and my previous car was a 2000 Boxster:
S2000
Loved the 9000 rpm redline, but you get tired of it if you are driving it everyday. The thing that bother me the most is the tail swinging out in tight corners. Great for drift racing, but not an everyday sports car. Also, the average age of owners seems to be in their 20's. I'm almost 40 and I don't feel right driving it.
350Z
I actually ordered this car in 2002 for the 2003 year. Drove the demo before taking delivery and cancelled the order. Nothing wrong with the car - good looks, power and handling, but just didn't like it.
M3
Fast car with loads of torque, great brakes. Heavy car, but power compensates for it. Good value for overall performance. Performance is at par with 997, but at 2/3 the price. However it doesn't have the sexiness of the Boxster. It's like Pam Anderson vs. Julia Roberts. Pam Anderson is not that great of an actor compare to Julia Roberts, but she has sex written all over her!
Lotus Elise
Handles like it's on rails and good power. Didn't care too much about the sound of the engine. Some people love it, but not for me. Quality feels like a home made kit car. Rattles everywhere and very tight inside - My shoulders were touching the passenger the whole time and I'm 170lbs! Great autocross and track car, but not an everyday sports car. Price is about right for it.
996 Cab
I always thought that this would be my next move up the food chain. Has more power on paper, but certainly does not feel like it. It actually feels slower. Doesn't handle as good as the Boxster and didn't care too much for the looks from the rear. It's also about $15K cdn more than my car for the same year. I'll pass this one for the move up.
997S, Boxster and Boxster S
Everything is right about the 997S - power, handling, braking etc. But didn't get the same feeling as the first time I drove the Boxster. I was dreaming about getting the Boxster for over a year before I took the plunge. Took another year before moving to an S. I'm very happy with my S and I don't dream about getting the car I want anymore........for now.
Well, I was lying, wishlist for my Boxster S
