Whether it's the owners that have ruined it for you, the design of it, the make and model... What really pisses you off?

For me personally, Fiesta ST150s. I've not come across one example that doesn't have a stupidly loud exhaust fitted and isn't driven by some knob who always wants a race.

I also loathe the A class Mercedes, has to be the most finaced car in the UK surely? And seems to be driven exclusively by the type of man that likes driving fast Infront of school girls.
