I'm lokking at purchasing my first air cooled 911 and I have some questions. The car is a 1974 with a full Rinspeed conversion, it only has 28,457 miles. Now the first question is it has a turbo badge which as far as I could find there wasnt a turbo in 1974. Also what kind of things should I know before I consider buying such a car and what things should I bee looking for. The car has an all red interior, but it looks like some of the red carpet has faded, where would I find replacement, not sure if Rinspeed was anything special on interior elements. I've always wanted an air cooled porsche, but have zero experience with them. Thank you for any help.
