Buyer beware? (I never did pay much attention in Latin classes, I was too busy seeing how the chariot races were going.)
I tend to be prety honest. When I sold the Rover I told the guy quite clearly what was wrong with it and how much trouble I had with it. He still keeps in touch and lets me know how its going in Spain. Seems I fixed just about everything that could go wrong and he's had quite a reliable car out of it.
(Should have kept it!)
