A few:
Peugeot 205 XS - great car, only went as missus wrote it off
Seat Ibiza Cupra - great car, rot box though
Citroen ZX 1.9 diesel (non--turbo) - the very worst thing I have had the misfortune to own, why people bought them new is beyond me- it was £300 though! I gave it away very quickly and I was still at uni so ££ was a bit low!
Audi RS4 B5 in Avus - my first of these, great but bankrupted me!
Skoda Octavia 1.9TDI - garbage really, but reliable
Audi RS4 B5 in black - the "Slowda" made me buy another - and I still have it waiting to get it back on the road
Audi TT 225 - bought for an ex, ended up keeping it. Hairdressers car and has had SO much work (which is why I'm loathed to get rid)
Skoda Octavia VRS 2015 - my first new car, albeit on a lease hire - good car really
Audi A6 3L BiTdi 2015 - my current daily and I love it - I've done so much work to it, I can't justify the S4 I want to upgrade to!
Lotus Emira 3.5V6 manual - my first new car I actually paid for. It's great, but has had it's fair share of Lotus issues.
I am sure I've had more, just can't think off the top of my head!
