I would agree, the Mk1 has a sort of exotica look about it and really does look like a muscle car too. Definitely a classic to be.
For me though, the Mk2 is more refined looking, in my eye's at least, it's a bit more classy and has a air of quality about it. I must say, that when I am out in the Mk1 more people seem to want to race you, generally BMW 330i types!
Just the other day, we were coming down the M5 toward home, a RS4 geezer flew past me, I was traveling with cruise on at 70, he then slowed, until I caught up and slowly over-took him, no sooner was my arse past his nose and he was there, in my mirror, looking to prove how fast he was, I pulled over to the middle lane and let him past with pleasant wave, you know, the kinda wave you do with your fingers in a loop! lol
