I don't know why 80k is such a special number in terms of mileage
Its down to the psychological 100,000 miles means a car is useless thing. By selling the car off at 80k miles, its far enough away from 100,000 for the next "average" Porsche owner to have a couple of years of use (maybe 4k miles a year), then still sell it with 8*,000 miles to the next guy etc.
I had the same dilemma when my 997 got into the 80,000 mile range. I figured if I wanted to sell then now was the time. But then I also figured once it goes over 100k miles then would a car with 101,000 on the clock be worth more than one with 116,000 on the clock? Probably not, which meant once I hit 100k miles it wouldnt really make any difference what mileage I did after then.
So, in the end I just kept the car. Its now got 101800 on it and im not ever planning on selling it. Its a weight of my shoulders now not worrying about mileage.
People always say buy on condition, not mileage, but in reality in the UK mileage does put people off. Condition wise, my car has just had a complete inspection and mechanical overall, with any worn bits which were flagged as needing replacement being replaced. And ive had a couple of garages comment on how good a condition it is underneath compared to some *lot* lower mile cars they have seen.
