Looking to buy a porsche 968 or 928S4/GT.. will be using it weekly in summers. Any su
 

I am looking for something reliable. I currently own a 1986 944 N/A, I have always done the upkeep and it has proven to be bulletproof reliable. By choosing a well maintained 968 or 928, I know the upkeep will be minimal yet somewhat vocom 88890300, and the car should prove to be very reliable. But I am looking to know from someone firsthand their impressions on these watercoolers. They are about the same price (although 928 S4/GT are going for a bit more..)
As I am looking to drive this car as often as possible in the summertime, I want a reliable, powerful ride. As economical as possible of course, although we are talking about two sports coupes. Best bang for the buck, best originality, best car...? Thanks for your input :)
