I always expect people to be mature and impartial like I am ;) Like I said before, just because we prefer Lexus doesn't mean we can't see the good in any other vehicles.
And actually the ES300 is much bigger than the A4, the ES300 is ACTUALLY bigger than the GS believe it or not. The A4 is really an IS300 competitor and the A6 competes with both the GS and the ES. The A6 has a lot of model range with pricing starting in the 30s and going to the 50s. It comes in a FWD 6 cyl version (like the ES), an AWD 6 (comparable to the GS300) , an AWD turbocharged 6, and an AWD V8 (comparable to the GS430). When I was shopping I seriously considered the A6 but never even drove the A4 because it was way too small, like the IS300, C320, 330i etc. They're all economy car sized.
Oh and before you say comparing the A6 or the A4 to the GS is an insult, they both WAY outsell the Lexus GS. You can be proud of your car and not be a big headed jerk by shooting down someone else's car out of hand when you really don't even know what it is you're shooting down. There are other cars on earth, and everyone likes something different. Just because you don't like a car doesn't make it bad. I dont like the GS, but I respect it as a great car. Brand bashing has no place here at the LOC, we leave that to the Ford vs Chevy people, ClubLexus, and mbworld.org. If you want to bash cars without having the information to back it up then sites like that are more your speed. If you want to discuss cars with a group of mature adults, then this is your site.
I can feel your friend's pain about getting the Audi serviced. VW/Audi requires special diagnostic equipment to repair, and its SO expensive that independent shops can't afford to buy it. So in a lot of areas you're really stuck with the dealer. VW/Audi's special diagnostic equipment is significantly more expensive than BMWs for instance...
Audi is a sort of "cultlike" thing, its almost like driving a Porsche or even a Ferrari, you've got to pay to play. Not me, but they're great cars....
