Sold a 13 yo car yesterday (mum's Aunt's old car, she has dementia). Its in very good nick with only 24k on the clock.
The buyer viewed the car tuesday night in the dark, put it in mums garage to get a better look under the light.
Paid for it last night and went away happy.
This morning I get a message from him saying there's a massive scrape along the length of the car and the car was perfect when he looked at it tuesday night. He then implies that due to my mum's unfamiliarity with auto cars that she damaged the car when she took it out of the garage. 
Also he had said that unless this can be resolved he will take legal action.
Im waiting for pictures from him to confirm, but im pretty sure he's referring to a crease in the door / wing that was already there well before he looked at it.
My reckoning is that he didnt spot it (twice) in the dark and is now trying it on to get a reduction on the sale price.
He has a letter of sale from mum (which he has signed) stating "The vehicle is sold as seen with no guaranteed expressed or implied.". I have photos taken in Jan which show the mark quite clearly.
So the question is here, what do I do and where do I stand?
In my mind I have the phrase "buyer beware", doe the fact that he has paid for the car and signed a letter accepting the car as it is cover my ass?
Your thoughts please.
