Need help on values

[drola]

i have a non-sunroof, non-catalytic 76 911s that i want to sell. stock 2.7 with all upgrades. high miles. have receipts going back to 1989. car runs well and strong and i drive it almost daily. i've done a lot of work to it to get it back on the road. i'm curious as to where i should start the price. car also has $2600 upgraded a/c that blows blizzard cold. it does have some body rust. underneath is clean as is the battery tray. here she is:





i have someone selling a 1987 g50 coupe. 105k miles. sport seats. been sitting almost 2 years and now won't run. i'm sure it will need tires and some brake work on top of what ever is wrong with the motor. seller wants 12k. i'm thinking 10k.
any opinions?
