I've never done any serious off-roading, like conditions where you would actually need proper mud tyres, or the good approach/departure angles of a big 4WD.

But i have done allot of driving on bumpy unsealed roads and ski field access roads where the rough conditions cause other drivers to slow down. The sort of bumpyness i'm talking about is where the ash tray keeps sliding out of the dash, the radar detector falls off the windscreen, hub caps fall off, portable CD players with "20 sec anti skip prebuffers" skip, and every thing in the car generally shakes and rattles and makes a huge racket.

I'm pleased to say that after almost 3 winters of this the empeg has never died on me, in fact it's never even skipped during those conditions.
