Ha. Monte is a friend. Aero coupe with 15k miles. Oops, you mean the white one (I have a black Aero too). The one next to the camaro was bought new, I pulled the engine with 3 miles then installed a 350 with Doug Nash etc etc.
I was going to say 35-40k as I saw a blk/gold 87 5.7 recently with 24k miles for $24k.
For me... It would be hard choice of a 87 Yellow over tan or a 89 Black over grey with the blue and silver stripe. BOTH are absolutely killer looking, however for the flash I would probably go with the Yellow as I have always loved it!
