For the last 15 years, my Uncle has had an 1989 Porsche 928 GTS buried in his garage. Worth the attempt to purchase and restore?

When I mean buried, I mean newspapers/bicycles/tennis equipment you name it. Backstory: I recently purchased an 95 e36 325i to have as a little track toy for a steal at 500$ but realized I'd like to daily this thing around. The project is coming to a conclusion to get it inspected and now I'm curious about acquiring my uncles Porsche. Is this car worth more than I'm anticipating or are parts hard to come by? Research I've come across is that it's a Chevy V8 from factory essentially so 60,000 miles doesn't even scare me and it's a manual. via /r/cars http://ift.tt/2sWfpUt
