I don't know about big day. I' having a non-running luxury car towed to my house, lol. This is after working all night and having gotten up at Noon on Sunday. I won't get a chance for sleep until probably 1 PM, and I've got a former side work customer coming by for a wheel bearing job at 4 PM. Ugh.
Those C5 (5th Gen, 98-04) A6's are pretty cheap. I never got into those though the A4's I liked enough. The C6 (05-11) were a HUGE step forward in quality and luxury, and were quite a bit bigger too. I'd give up a nut to have a late gen RS6.
