He was an older guy who drove this car, I've seen him driving around. I checked it out as well. The stories seem legit. The upside is the low miles, the downside are the repairs. I guess they wash out.
Good luck on the PPI. There are some get together for local southeastern MI M3 guys, PM me if you do pick it up and want to meet up with other local M3 owners for some drives.
