Got mine at 52. Clutch had to be replaced...50k seems to be pretty common.
Plugs got replaced which uncovered valve cover gasket leak. Runs much smoother though with new plugs.
Just last week changed Transmission, differential, oil and power steering. Shifting is smoother now.
Previous owner had MAFs replaced and a break job at 46k.
The 40k to 60k range seems to be a bit expensive but all is well now so hopefully I can cruise to 100k with nothing but optional expenses.
