The blue car PO:
Taken to the dealer religiously to repair ANYTHING that wasn't perfect. I always remember the receipt I found for a $257 shift boot. The car had belt service, clutch service ($955 flywheel), interior service, and being a stealership, they also gave her a good posterior service. When we bought the car, it had 220k miles, but it looked like it had 60k miles, inside, outside, engine bay, I kid you not. No goofball evidence has been found.
The red car PO:
The well known Bill P in the bay area. He had 5 other 968s at the time I bought his 6th one. The car had no problems at all when I bought it, and in 2 years of ownership it is still fine. The car was well taken care of and super clean. I remember noticing there was a little microphone installed in the cluster trim piece, over by the temp gauge. I asked him about it, and he said he never even noticed it, and it must be some kind of CIA spy device. But he was cool, talked a lot about Porsche history and his own ownerships of many different porsches from way back in the day. He called me a month later and a year later to see how the car was going for me. No goofball evidence found.
We just got lucky with the POs I guess.
But on my (now sold) 944, there were T O N S of goofball birdbrain things. I loved the fender sprayed with the totally wrong shade of red.
