As an owner of a 930, and having 4 very close friends with 930's as well, I can tell you there a number of things to watch out for when buying. They are not cheap to maintain, but very addictive to drive.

Your best bet is to go with the '89 in order to get the G50/50. Mine is an '86 and had the G50/50 installed (thank you Jim Patrick) and I've driven many of the 4 speed cars. The difference in the shifter feel and clutch are significant, not to mention the closer gear ratios in the G50, especially noticable with an unmodified engine.

When compared to a 3.2 carrera, for example, you shouldn't expect the motor to last nearly as long. The valve guides will wear significantly faster because of the higher temperatures especially when driving hard. Clutches don't last forever, and depending on the care it's been given the turbo charger can wear out quickly too.

The best thing to do is have a PPI performed by someone familiar with 930's. Not all qualified mechanics are intimate with them, primarily because they are rare in comparison to NA cars, so make sure you find someone who works on them regularly.

Good luck.
