Here goes:
1995 passed test at the age of 20 and didn't muck about; I went straight into an extremely powerful car - the fastest on the road at the time if I recall: Nissan Cherry 1.3 SGL

(the SGL part is extremely important as it meant I had a rev counter - lol!)
After this I had the following but can't give exact dates:
Nissan Cherry (first car)
Montego 1.6L (for work)
Montego 1.6L (both very, very nasty and engine technology dating back to the 60's I've been told)
Rover 400 (bubble shape 416Si) on which I spent a ridiculous amount of money on Head work, mad cams, straight through exhaust, induction kit etc. etc. etc. - and after all that, was just about as quick as the equivalent 420GSi so was hardly bloody worth it!! Would have been far cheaper to just buy the bubble-shape 420 in the first place!

Rover Coupe Turbo (Jap spec, rare FDH plate with full leather, air-con etc.)
Rover Coupe Turbo
Rover Coupe VVC (which, after fitting a K&N induction kit, made a fantastic sound!)
Citroen ZX Aura Estate 1.9 TD (for work)
Audi A6 1.8T (which didn't last the trip home from the dealer!)
Replaced above immediately at dealer with a Nissan 200SX, which was frankly lethal in the wet!
VW Golf Mk4 Estate 1.9 PD130 TDI (work mainly)
Audi A6 4.2
Audi S8 Final Edition (D2 platform) - which I still really, really miss after over a year with the RS6 plus!!
Audi RS6 Plus - fast, head-turning, loud, but somehow not as special as the S8 - it's hard to explain but think it is to do with the handling and feel of the S8 - you could really 'feel' what was going on underneath you and that made it a real joy to drive everytime. The RS6 helm is pretty numb, even with coilovers I'm afraid..
Where do I go from here??
That's easy: Will most likely be the current (D3 platform) Audi S8 with carbon ceramic brakes hopefully (and once used prices drop - alot). And just have a listen to this - it's a D3 S8 with a full Milltek and is THE best sound I have EVER heard from a car, period:

Wonder how it'd compare to the '6...
