low compression in 1 cylinder on e36 m3

[ber55ber55]

Well im gonna get rid of my e34 535i soon, and I wanted to buy another e36 m3. IT is by far my favorite car over all the sports cars I have driven and owned. I am looking into a used one that I found. It has one major problem though. Low compression in one cylinder. How serious is this? I dont know which cylinder. My m3 at home has bad compression in all 6 but it has 100k and was owned by a dumbass before me. How much would it cost? its a 95 with about 129k miles on it for $7k. Buy it or not? I have the money in my pocket haha...

it can be a bad valve or a bad piston/rings, ether way it's not going to be real cheep, bad valve is cheeper if it didn't take the head out
