opinions wanted; car sales gone bad

Hopefully ya'll did a bill of sale with all the discrepancys listed and stateing [as is where is] several times with both yours and the buyers signature on it and the vin number. As far as the speedo i'm unsure how they [dmv/courts] would look at that [do you have a recept for the new body control module] that should explain the speedo issue.As far as the sale you [did what most honest folks] would do and the buyer is now having regrets in his purchase. I have been lucky in my dealings to never had this happen [but i cover my butt three ways to sunday] but the worst thing that can happen is he takes you to small claims court [if you have that in Canada] and if you have proof you told him and wrote it on the bill of sale you should be ok, but if not be prepaired to get the auto back and give him back his money plus what he has spent and court costs. So if you don't think you can win in court then you need to make this guy go away! Some times Craigs List brings out the crazys.
