I don't know. I have a few Shipmates and a Master Chief with BMW's bought used after deployment, and they run great. I drove MC's BMW and it ran like a top.
You can't blame the car if the owner is too stupid to pop the hood and pull a dipstick. Heck that would even go for a Yugo. But I would think an owner of a Yugo would be lower on the food chain, and lacking brain matter compared to a BMW owner. JMO
