Definitely talk to an atty AND talk to the bank who 'wrote' the check asap, as like other checks, it "may" be cancelable...

It's sad as litigation is rarely easy or quick, and that is almost assuredly where your uncle will need to go. It sounds like he may have some...

Good luck proving it? Probably best to fix it and sue for that price difference or to maybe sell it for parts?

You can try to back out of and unwind the deal...

Try hiring an atty to write a strong demand letter...

I'm sure you can, but, it sounds like you have not discussed this with him? That should likely be your first step imho...

In addition to what has been stated, it MAY be possible to shoehorn this into a fraud claim or an employment law claim, MAYBE... A consultation...

Sure. Sue away! Good luck with it...

So, of course the answer is MAYBE! Did you VOID your insurance policy by renting our your car? If not, make that claim and let them worry about...
