Low K’s on the clock means nothing.
Look for the obvious signs, ware and tare on the seat, footwell mat, steering wheel, seat belt. It’s not hard to see what’s been tampered with.
I recently brought a 18 year old tow pig that showed 117K’s on it. The condition reflects the klm’s. As everyone knows, if it’s to good to be true it usually is, run away.
