Porsche 993 C2S
Hi. I would definitly recommend that you buy a 993 C2S. You may have to pay a bit more money but it will only go up in value. They are the last of the widebody aircooled Porsches. And you are right, the 993 C2S is by far the nicest looking Porsche ever made.
If you buy a 996 on the other hand, it will depreciate.
I have had many Porsches throught the years. From 996's to 993's to 356's and I recently sold my 2005 997 and I recently bought a 1998 993 C2S. I am from the states & 993's are very hot in the market so I paid alot of money for the car but it is mint, ocean blue, a perfect car which is a great investment to me because it will appreciate in value. I named the car "Fratt's Horse Buggy" because of the widebody rear fenders & split twin grille, the 993 C2S reminds me of a roman chariot.
Anyways, good luck to you in finding a nice Porsche and hope you can find a nice 993 C2S. There are some nice 993's for sale in the US. Look on ebay motors, autotrader, ect..
