what mileage before car not worth buying?

i know 12k a year is considered normal but whats your opinion on buying a 10yr old with 120k on / service history good , ,baring in mind its 1st 911 & its likely to be doing 3/5k a year , what kind of mileage before engine/gearbox overhauls are likely?

Hi, Porsche's book at 8k/year, not 12k....so you need to take that into account. There's a few people on here that have had faultless engines up to the mileage your talking about. Porsche warranty engines up to 120k miles, but no more. A new engine is about 6-8k fitted, so you need to consider that as well. I wouldn't consider such a high miler unless it was attractive enough on the £ front, I was going to keep it for the long run and I had enough spare cash to replace the engine (which will invariably go at some point in the future). On the positive side, if it's a high miler then the wear and tear will be reasonable on the rest of the car (assuming it's motorway miles). In summary, I'd consider one if the price point was attractive enough.

I bought my 930, 87 turbo on condition its now done 93000 in twenty years.It had the top end done a few years ago. For me its the every mile is a smile a car is to be driven and enjoy. SEE YA

Buy on condition and history. Engines are robust if looked after. At the Silverstone Classic a 911 Club Sport on display , had covered 400K miles with engine rebuild at 280K! Still had original crank, cams in engine. Looked superb, you would be hard pressed to pick it out of line of same age cars with low mileage. Any car that age check for rust
