1976 Mk 1 1.6LS VW Golf (well, approx 70% of one, the rest was holes and rust. £80 deathtrap). Worst car imaginable; I personally watched it get scrapped.
1977 Mk 3 Ford Capri 1.6GL (2.0 'Pinto' transplanted on Day One of ownership, natch, as well as a complete interior and six-clock dash transplant from an "S"). In Apollo Green, with slot alloys and Janspeed 1-box. Still my favorite ever car, more than any of my Porsches, I cried like a baby when I sold her ("Bev")
1985 Mk 2 Vauxhall Astra 1.3GL (the egg-shaped one with self-destruct camshaft)
1983 Mk 3 Ford Capri 1.6LS
1978 Rover SD1 V8 (absolute piece of shit)
1990 Ford Fiesta XR2i (loved it)
1993 Mk 3 Vauxhall Cavalier 1.8GLSi
1992 Mk 3 Vauxhall Astra 1.7TD
1993 Mk 3 Vauxhall Astra 1.8CDi
1997 Peugeot 406 1.8LS
1999 Rover 200 2.0D
2000 Renault ClioSport 172 (loved it)
1997 Mk 1 Renault Laguna 2.0i estate (comfiest cheapo barge ever, loved it in its own way)
2002 Audi TT Mk 1 225-Quattro coupe & 2003 Ford Mondeo 2.0TDCI Ghia X (absolute shite car, massive engine problems that Ford walked away from. At least the Golf only cost £80, this fucking lemon cost £14,000...)
2004 Audi TT Mk 1 V6 convertible
2008 Audi TT Mk 2 3.2i Quattro V6 coupe (good car) & Fiesta 1.4TDCi Style for Mrs C
2007 Mk 1 Cayman S 987.1 (gen 1) - fucking awesome, converted overnight & Mk 6 VW Golf 2.0GTTD for Mrs C (utterly soul-less, handled like a blancmange, not sure where the "GT" bit came in TBH)
2011 Boxster S Black Edition, 987.2 (gen 2 with high compression engine) - giant killer, Top 3 car for me & RR Evoque Tech SD4 for Mrs C (surprisingly a very good car)
2014 Mk 2 Cayman S 981 - you gotta love it, best handling car I've ever driven & RR Sport TDV6 3.0 for Mrs C (ahem, brief Audi A3 1.6TDI Ultra ownership
)
