I'm not familiar with this particular car, but I do have SPC0123. From looking at the photos, I can suggest some info you need, and several changes you should make if you buy this coupe. First, find out who the installer was. There are a number of good ones, and at least one not so good one. Make sure you get the owner's manual, knock off hammer, and jack with the car. This car has the stock PS unit, which should be changed to a pump with a remote reservoir (fluid will run much cooler) and a different pulley. If it has the stock fuel pump in the stock location, it needs to be moved to the same level as the bottom of the tank. If it has a Holley Red fuel pump, you should eliminate the fuel regulator - it's not needed and will not operate properly with the 7 psi internally regulated Red pump. You will probably need to change the heater control valve. There are other helpful mods but this isn't a convenient place to describe them.
Finally, there are no external door locks on the early cars, so if a door popper fails (and they do) you have to crawl in through the hatch.
I would also want to know why the owner didn't drive it!
They are a blast to drive (and comfortable, too), and you will never lack for onlookers and questions ...
