As for reliability, grab yourself a copy of vcds and use your laptop to carry out a scan every so often, you’ll soon save hunks of cash and, IMO, always nice to know that the car is working in fine fettle whether the management light is on or not.
A very good friend of mine owns an older A6 2.7tt and despite only 250bhp, it’s an absolutely stunning car to drive, so so well built and does high 20’s taking it steady.
So while not to the same financial outlay some of you chaps are comfortable with, they’re cracking cars and can be had for good money if you keep your eyes peeled.
Had a 20v quattro coupe some time back too, hammering around Derbyshire at about 5am in the summer, lovely 😉 windows open, 5k rpm, awesome!
