I wouldn't do it unless you do all of the "wrenching" yourself. Guys who own them around here as daily drivers and rely 100% on a "Porsche" shop ay they spend $3,000+ to keep them on the road. And I would worry about the 915.. the R&P s are approaching unobtanium pricing. You should consider a compromise, like a water cooled 911 cab for $15K. I would have considered that $15K very high mileage G50 coupe backdate. With most of the 911s there will likely never be a catastrophic failure that will cause you to abandon the car.; it will make sense to revive it. The Evo's cost of ownership, on the other hand, could be quite high with depreciation.
