It last, after 18 months of research, search, dither and worry, I have my 993C4 and I'm very happy.
Actually I got it a couple of weeks ago but I've been too busy driving it to post anything here!
Thank you to everyone who contributes to this forum. By the time I had been reading this for a while I felt much more confident that I was making a rational choice.
Looking forward to learning a lot more now.
Experience so far has been so different from anything else I've driven, although the only "sports" car I've owned was a 1970 MGB-GT about 10 years ago, so I don't have a lot to compare it with. Unfortunately, driving my 2006 RAV4 (which I used to enjoy) is now like using an electric lawn mower. Anyway, I've seen another post that says other cars are just for when it does not fit in the 993.
I live in Scotland so really wanted this car for driving way up north. I'm used to packing a lot of climbing or mountain biking gear in the car at weekends, I need to find a way to cut down on gear!
