1 track day
3) is there a dealer near you that could do a pre-purchase inspection?
yes, beverly hills porsche.
4) anything with the car inside or out that marks it as not new? dents, paint chips, rim scrapes, spills, stains, tears, etc?
No stains or tears. There are a couple marks on the clear bra, just from normal stuff, but if you took off the clear bra they wouldnt be there (basically did its job). The back of the seats have a couple marks on the bottom backside. And a couple of light scuffs on the passenger side center console, very very hard to notice or see. That is it.
