Good grief...that interior looks as if its come out of Huggy Bears Caddilac.
Lovely exterior colour..looks like Bornite to me...my favourite colour on early 90's Mercs.
One thing that strikes me as odd when reading the write up is the removal of the seats, painting of the seat frames, cleaning of the carpet and sorting out the electricals for the seats......could this indicate that this car has been wet at some stage hence the need to repaint rusty seat frames, deep clean the carpets/dry them out, and sort out water logged electrics?........or it may be that the guy is just very, very thorough as the rest of the car appears to have been cleaned just about everywhere else
