Question - how do you deal with private lots that prohibit people working on their cars? I know my community has restrictions against this - I've never run into it myself doing simple things like checking oil level and such but I wouldn't attempt a major service like timing belt replacement in my community (hence why I find a friend's driveway to do such work in :-P). How does YM work around this?
