my worst was a MGB GT. bought it to replace a 63 Ford Zephyr as I wanted something sporty... it was 'rubbish' so much so that even though it was a shiny decent condition example 9 months later I picked up a shed of a Triumph Vitesse 2 Litre and walking out each morning with both keys on teh keyring I got in the Triumph 90% of teh time, it was rusty, it was thirsty, it didn't handle ina good way but it was soooo much nicer car to drive.

Luckily I've avoided most of teh boring stuff as I was always into classics and sporty stuff.
