First of all, a 1984 911 is not an SC, but a Carrera debuting Motronic DME, which is a modern engine management system. Prior 911s utilized CIS injection, which was fine when working properly, but a bit of a pain otherwise. I've owned many examples of the eighties Carreras and never experienced any major repairs. Cost of parts is certainly not overly expensive due to the massive aftermarket following of these great autos. As I mentioned previously, check for worn valve guides, as this is one area of trouble that could show on these engines. I have many friends that have rebuilt their own engines, as they are not overly complicated nor terribly expensive to repair, compared to the M96 (bang and done). These cars are rock-solid and great fun to drive, but not really a daily driver. AC doesn't work great from the factory, but there are numerous aftermarket solutions that don't alter the physical appearance of the car. If you want a modern ride with your latte and iPod, maybe a Carrera isn't for you; however, if you are longing for a true air cooled experience, this is the ticket. Don't bother with the 996 models, Boxsters are more fun to drive.
