There is a champ that the SC has, I love the way the 3L revs with little effort. I love the old classic feel of the car as well as the older look.
A 50-60K 964 or a 60-70K 993 is just out of my range. I bought my SC last year so I am at the top of the bell curve, and prices on the impact cars seems to have stabilized or ever cooled, besides I do love the car, its like a great song that you just want more of ya know.
I think moving toward what Jeff has suggested in the future would be the smart bet along with some TRE bumpers and light seats, getting me under 2300lbs.
I was planning on searching for a Cobra kit in a few years or so anyway to get my cheap hair on fire fix. So keeping the Porsche more inline with where it is now might make the most sense, and maybe learn to appreciate what I have a bit more
