Located in Ontario, by the way.
I bought a 2001 Honda Civic about a year ago, i had a new motor, new starter, new alternator, and new battery all put in the car and put some rims that I 3 grand when I bought them on it. It had NO signs of problems after all the work. About 4 months later in the summer my cousin offered to sell me his Mustang so I wanted to sell the Civic. A guy about 18 years old looked at it by himself, then the next day looked at it with his dad, I even let his dad test drive it and they were excited and loved it. I sold it for $2500 (cheaper than my original asking price because the body isn't perfect).
Two weeks later I get a text that the car overheated and he was stranded because he drove the car all the way across the border to the States! It's been a couple months now and he's taking me to small claims. The bill of sale says as is, and we both signed it, both have a copy.
The car showed no signs of problems with me and I don't know if he had the car inspected before driving it to the States.
What should be my course of action? The car was great when it was in my possession
