I'll recount my buying experience, just to reinforce what many people have said on here already.
I've spent about the last 25 years tracking the prices of 911 ! I've seen 1960s being sold for about £8k, 930 a little more, 964 were bargain basement and 993 were mid teens. Turned down a 996 GT3 a track machine that was being sold for £27K with all the parts to return it back to a stonking road going machine.
Anyway, it's not about what if? I bought my car back at the end of February. I'd seen a few cars already, a few owned by forum members. Eventually I found a car that ticked most of the boxes, the only thing was, the colour wasn't my first choice (seal grey, I wanted lapis blue), but it was in reasonable condition. Had recent money spent on it, like a free flow manifold, 200 cell cat, sports exhaust, new MPS2 tyres all round, genuine turbo hollows, manual, Bilstein PSS 10, new rads and condensor and mileage was fairly low at 70k miles for a 2002.
I knew it was due a service and an alignment. I spent £3k in the first week on a new clutch accumulator, window regulator, heatshields, fuel cap, brake fluid change, some ducting and undertrays were missing, CV boots, ARB drop links, coolant leak (rads were plumbed in upside down apparently).
After that I spent another £3k on an uprated clutch (RMS was leaking and causing the previous clutch to slip), intercooler and brakes. Car had a poor tune on it, which I've had rectified.
So I paid under market rate when I bought it and ended up with a car that is (almost) tip-top. Monetarily, it would've cost me not much more to go for a fully sorted example with a well regarded independent dealer tbh, though some of my spend were not strictly necessary, like the brakes and I could've saved a few hundred by replacing with the standard clutch.
