Would you bypass a PPI if...

[Perfectlap]

I would be a hypocrite if I told you to do it because I didn't do one myself.
My car was spotless showroom condition (literally sitting in the showroom), a trade in at a local Acura dealer I spotted on Ebay Motors. Only 10K miles and EXACLTY what I wanted: very low miles, 3.2 engine, silver and red.
When I arrived at the dealer the young salesman and I had no idea what we were doing in trying to "inspect" the thing.
The car was up for auction and I was convinced it would sell so I didn't fuss with arranging for a PPI. BIG RISK.
The funny thing is the car didn't meet the reserve by barely a hundred dollars. I wasted no time (having dodged a bullet) and negotiated a price within a few days.

If you have the luxury of time and being the only guy interested then by all means get it inspected by your local Porsche dealer. Its a small price to pay for piece of mind. And if they find something that needs fixing you can negotiate that repair into a lower purchase price. So the inspection could save you money.
There is a glut of low mileage Boxsters on the market, get it out of your head that this THE ONLY mint condition Boxster. It simply isn't.
