I didn't. I've still got the TVR. I bought the Z4 to run as a regular car (shopping, getting about, whilst still having fun).
I've been running a tuned Pre-Cat Griffith (Stage 4 heads, custom manifolds and exhaust, fully mapped ignition, carbon trumpets, carbon plenum, carbon airbox, triple Jenvy throttle bodies, K&N custom induction) for about 10 years and it's not really suitable as an run about. She's getting on a bit (20 years) and needs some TLC this/next year. So I wanted something fun and reliable to use. Plus the gf can't/won't/isn't allowed to drive her.
I work from home so don't drive too much.
Usually I ride a motor bikes, but since moving in with the gf, she's not too keen on the bike in winter.
Done a few years back now, the wadding in the exhaust has sort of gone.
