just sell it and buy another one.
Heres a personal story:
in the purchase before i got my accord, i bought an audi A4, it was a lemon with 66K kms on it - even from a dealer. sold it 3 wks later, and I lost $3000.
So $1000 a week. So thats A LOT worse than the 'issue' u r faced with.
Sure he may have misrepresented, but u HAVE a running reliable car that looks great and handles comparatively good. Like a house becoming a home due to ones love for it, your purchase can also become your pride and joy.
