We had chap who bought a SLK off us two years ago , super thing and we had driven it 70+ miles too so knew it very well , he took it home to Kent 250 miles away and rang us to say the rear diff had gone on way home , Luckily my son was down Kent on Hols so was knocking on his door 15 mins later asking to drive it , The chap was devastated as clearly it was a scam , The surprise he got was worth the call the scamming old git , Nothing wrong with his car at all just after some money
