Oh my...I did it again.

Update- been daily driving this car and loving it. Big smiles driving around town.

Upon further inspection, I believe this car is a low miles original (86000 kms). It still has factory markings under hood and in the door jambs.

For us factory markings nerds...Some pictures of the markings I have found that make me think this car is low miles:

Under hood black grease pencil or marker? Now I've had cars that have had markings like this survive up to 100k plus. Note the late big block heat shields to help prevent the dreaded valve cover gasket failure and leaks.
Drivers valve cover "BM?"

Passenger valve cover "253" in black and a white "X":

LB Computer "88" in black:

Now for the door jambs...I've never had a C body where these have survived by the time I owned the car...in red or orange grease pencil?
