I think there is one of these threads every couple of years. It's always fun to reminisce but, the older I get, the less cars I can remember. Here's my best attempt, car history from 2003 to 2017.
1998 Ford Mondeo Ghia
1997 Vauxhall Omega V6
1993 Citroen ZX 16v
1993 Peugeot 405 SRI
1994 Vauxhall Cavalier
1999 Vauxhall Omega V6
2006 Audi A6 TDI (lease)
1999 Mondeo V6 Ghia X RSAP, ridiculously lowered, cost £460. Loved that thing.
1998 Fiat Coupe 20vt, boost wound right up, loud exhaust, also very much loved until I crashed it
2006 Ford Focus TDCI, bought as a self-imposed penance for crashing the Fiat and nearly killing myself. Didn't last long.
2011 Audi A6 TDI (lease)
2003 Audi RS6 Avant (cost £8k, spent £10k running it, sold for £7k)
1992 VW Golf Rivage Cabriolet, heaviest non-PAS steering of any car I've ever driven
2003 Madgwick Roadster kit car, chassis wasn't square so it crabbed along the road
2009 Audi RS6 v10, the longest I've ever kept a car which says something about how awesome it was. Never missed a beat.
2015 BMW M5 Competition now with cat delete pipes, milltek, remap and ceramics. Just under 700bhp. Still got.
1994 TVR Griffith 500 now with standalone management, uprated injectors, cat delete, almost making the claimed stock power. Still got.
1995 Ferrari 355 Berlinetta with Capristo exhaust. Beautiful retro Ferrari, 27k miles, sounds like an F1 car. Still got.
2014 Ferrari 458 Speciale, Rosso F1 2007, carbon buckets, carbon everywhere, epic in every way. Still got.
2016 Tesla P90D, it's the future but I can never bring myself to walk past the Ferraris and get into it. Currently on sale-or-return with a dealer.
2015 Range Rover Autobiography, wifey's car and the only thing I'm allowed to take the baby in.
... and last but not least, a new addition. My dad (dearly departed) had one 25 years ago and now I have an almost identical example.
1987 Nissan Bluebird ZX Turbo.
Definitely missed a lot of cars here.
