opinions wanted; car sales gone bad

I'm guessing the car was due for an inspection, and he was still using the car personally. At the time, he would have no idea whether it would take two weeks, or two months to sell it. Here in Ontario, we don't have annual or bi-annual inspections. Vehicles only get inspected when they change hands. The safety certificate is only valid for 36 days here. (Ontario). The buyer knew the car would coming with bald tires, and it was up to him to get them. In the time the buyer has had the car, who knows how he has driven it. If he managed to blow all 4 struts and consume copious amounts of oil, I'd say he wasn't easy on it!
You can speculate all you want, don't mean a thing. I was trying to go on only the facts that have been presented.
