My mom has no idea what she wants but she drove an A8L 4.2 and really loved it. The thing is ridiculously loaded and I think she should go for it. Anyway, what are the potential issues with it? She has an indy shop that she trusts so assuming there's nothing that could go catastrophically wrong, she isn't that concerned with overall maintenance costs, especially since she's used to $1500 services for her old E46 M3.
