Largest engine in an estate car?

Just wondering. AMG Merc? Audi? Yank tank?

OK, so let's add some rules. It must have been in mainstream(ish) production and readily available from a showroom.

Doesn't have to be in current production!

I don't know the answer by the way

[Garlick]

Vixpy follows LHD Will, you should know that by now

No fancy quoting eh?
