Price is about right, assuming that the tub is in good shape....lots of goodies, according to the ad.
I love these cars, but I'm prejudiced......because I love these cars.
It would be good to look at the rear spring mounts (for rust) and look over the entire car for serious crash damage (if it's been a racer since '73, there will be some damage...just be sure it's not too bad).
The 'glass nose and rear flares may not be OK for most vintage classes. Switching back to the steel nose is easy, but re-installing the stock rear steel fenders is a pretty big job.
If you end up buying it (or another racer) and you want to get some good track time, I can recommend a great little race club that's very low key (and most of the vintage clubs accept our race licenses).
