REALLY nice 85 D I'm getting ready for a customer to sell

[vstech]

I'm going to totally detail the engine, and steam the interior. any important items I should focus on to get in perfect shape before the listing?
I wanna get maximum dollar for this guy.
it's a topaz metalic blue sedan, low miles, fantastic shape, everything works on it. sad story, the man has several MB diesels and a few VW's, and he wanted a D for his wife. he found this one, and she loved it. then she died.
he's kept if for the last two years in the garage, and the paint is perfect, he just wants to sell it.
soooo, all helpful hints toward restoring this baby for sale will be appreciated.
