PPI should be done at a Porsche specialist shop familiar with aircooled turbos. Don't pick the shop where the PO (previous owner) gets his/her work done; the shop's allegiance may be to the PO, and not to you.

930 can be used as a DD. You won't have working airconditioning and the comfort level found in even a modern econobox, but there are only a couple times I've ever regretted taking the 930 to work. Peoples' complaints about having "only" a 4-speed gearbox on the pre-89s is garbage.

Wrenching is only mildly more difficult than on a similar-vintage 911. After all, the chassis is still essentially the same in how stuff is put together. The turbo charging is a little more complicated, but not overly so. It just takes a little time to take that stuff off to access other bits. The car is a bit of a mix of eras, though. The body in my '87 is similar to normally-aspirated 911s. But the engine uses CIS as its fuel injection system, which was found on earlier 911s. So one minor complaint is that there's no single shop manual that addresses the 930.

Cost of maintenance isn't prohibitive. Again, the chassis is still essentially a 911, so it's laid out like a 911. The cost of oil changes, brake fluid changes, brake pads, transmission fluid, etc is going to be roughly the same, turbo or no turbo. 930 specific parts cost a bit more, but aren't totally ridiculous. But, you have to realize that all that high heat in the engine compartment means stuff wears faster. Don't expect a 930 motor to go 200-300K miles, like some boast about their 911s. And a rebuild can run $10-25K, depending on what the damage is and how much while-you're-in-there you want. It's nice to have roughly 260-300bhp from a stock motor. It's nice to be able to bolt on things like an exhaust/headers, turbo, intercooler, cams, etc. and get another easy (if not cheap) extra 50-100 hp.

I can't give you a definite annual cost for maintenance and repairs. I've taken it to the shop 3 times in my 20K miles of ownership (not including tire changing and alignment, which I can't do at home). Maybe a total of $2000 for those 3 unscheduled visits. The other semi-big ticket item was replacing the four CV joints, which I did myself one afternoon (and evening). That cost maybe $500.

No snow experience. I'm in California, and didn't drive the car in the salt when I was in Mass.
