Fair Price for 911sc

I hope this isn't an inappropriate question for a technical board, but I've recently ran across a 1978 911sc Coupe that I'm interested in buying. The car has 130,000 miles on it, the paint is in very good condition, the interior is showing some wear, but is in good shape for the age and mileage, the mechanicals seem wonderful, the suspension/steering is very tight and the engine sounds great and doesn't burn any oil. The only obvious problems with the car are a non-functioning air conditioner (unimportant to me) and the power antenna doesn't work (even more unimportant). I'm not sure if the car has had the chain tensioner, release valve, and spring clutch mods done (which seem to be the essential ones from my research), since I have yet to talk to the owner (her daughter let me drive and inspect the car and she didn't know any of that information). Assuming those modifications have been performed does $9,000 seem like a good price? Thanks in advance for any replies.

According to Porsche market update in the August 1999 Excellence a 1978SC purchase range is low 9157, good 10411, and excellent 13938. With these figures, it seems the car in question is a good deal.

i have a 1977 911s yellow...it is in great condition with tensioners, 11 blade, pop valve, etc. the body is in great shape, the interior is in good shape, and the vehicle has 138k miles, how much is this car worth in excellent condition...

Really the best way to find out the "going" price of any automobile is to check on the latest issues of Excellence Magazine, in which they publish the price of every Porsche model, of every year, with three ranges from low to high.

Read these reports carefully, for the price of any auto depends on what a customer is willing to pay. There are no absolutes with used cars. Cars which are more "rare" will command higher prices than "ordinary" cars, cars which have been well-maintained will command higher prices than badly-maintained.

When all else fails, just ask youself the one important question "If this were someone else's car, how much would I be willing to pay for it?" That usually will put the "value" of your car right into the ballpark.....Andras

Way, A 1977 is valued low-$5963, good-$9076,excellent-$12150. As you can see there is quite a bit of variance from low to excellent, the milage may play a factor in these values. Prices from August 1999 Marketplace in Excellence Magazine.
