Would you buy a Morgan unseen???
Any Morgan.....
BTW I've never heard of a +8 lightweight
1976 +8 lightweightNo of course not

especially if it had been subjected to a heavy collision as the OP car has previously....
The lightweight Plus 8's were made from 1975-77 and the weight difference was Standard 1,950Lbs and Lightweight 1,835Lbs with 195 - 14 wheels and tyres . So a crash diet difference only..
