I'm crossing over from the 6er board since I own an 87 - 635CSI. Question, I previously owned a 1986 735i and I saw a 1986 L7 listed in the local paper for sale which I'm thinking about looking at to buy. I've seen pictures of an L7 and it looks a great deal like a 735i. Are there major differences in the cars other than like interior upgrades, like different engine, suspension, etc. I had a lot of A/C problems with the 735i which most A/C repair shops wouldn't even look at, and that's why I sold the car. Any input from you guys would be appreciated. The 6er is more like a sport model and I kinda miss the real wood and ride of the 735i I previously owned.
