Little street terror.

I can see this one both ways, I guess. Personally, if the current owner/seller new how to take care of the car, had it for years, worked on it, etc. that very mild burn out would be 100% fine with me.

Looking at rental cars for example, certain kinds of people will abuse other people's property when they think they can get away with it. I see absolutely no reason to think the OP is one of those people...and as has been pointed out, it's still his car! Just my opinion.

On the other hand, if the deal included fresh tires and/or new brake shoes, then yeah, this might be affecting the terms of the deal that were agreed upon.
