If you are even thinking of the 87 944 you should pass.
Market value=$2500 tops in cherry condition. i.e. does not retain value
repair costs=$$$$$$ seriously guy you may know the cars based on specs but when it comes to matinence and repairs 944's as well as 911's are not cheap by any stretch of the imagination. In fact it will cost you 5 times more than the cost of the car to get the engine rebuilt or even buy parts and do it yourself.
Unless your wealthy and have lots of cash to throw around don't go there.
If you seriously do like the 944 then you should be looking at a S13 hatch because its in the same weight catagory. You will pay the same price it will retain its value and you can put a SR in or turbo a KA for less than rebuilding your beloved 944 and it will kick the 944's ass . Yes S13 hatchs are that good .89 on the skidpad stock with suspension they are G+ machines add bigger brakes and a turbo engine and its bye bye.
944's have no value because your basically buying a car that should have been made in Japan and has the Porsche name so your getting stuck with a automatic expensive parts price tag.
Word, your going to buy a Porsche? 911's or 914's (914's are go karts
)
