The car in question will only be used at the weekends and I would prefer something that has a sense of occasion, the power to actually make you want to drive it any chance you get with a track day or two per year and travelling around Europe in it.
My budget is £15, 000 and it has to have more than 4 cylinders

The Audis' in question are as follows:
A4 S4 B7 4.2 I first considered the B6, but the B7 can be had for as little as £10k with less than 100k miles on and with 40/60 torque split between axles.
Would have to be an Avant for looks

A5 S5 8T3 I like the exterior and interior design compared to the B7 S4.
Don't need the practicality of a 4 door and if my facts are correct the V8, though similar has FSI technology and is susceptible to coking.
Sub 100k for 11k
A4 RS4 B7 Prices start at 15k for 110k example.
RS4 for the price of a B8 S4? 420 Bhp from a V8? I like the sound of that!
What does concern me is the fact that when they were sold they were sought after by tea leaves. Is that still the case now with them or have other, newer cars become the target of their fixation?
I am aware of the issues with DRC, coking and replacing brakes. Did I miss anything out?
A4 S4 B8 15k For a supercharged V6, faster and from what I read a better all-round car than the B6/7 and better looking... but misses the V8 growl.
A6 S6 C6 5.2 V10, well-equipped and rather fetching in Avant form.
Going by the size, weight and the fact that it only comes in Tip-tronic form, does this take away from the driving experience and is it any less fun to drive than the above?
I know each car has their problems, what car doesn't, but which would potentially offer me the most fun and not worry about where I leave it.
I live a flat with a shared car park of 40 spaces in the centre with a barrier... though I'm dubious about leaving it there as some people park pretty close to my current car and I have seen someone open their car door into mine because of this

Any advice would be appreciated as it's doing me head in!
