Judging by many things not including performance, the Porsche 911. Good god, so many of them about in various guises, they sound dreadful like the engine is on its last legs, look so dated (I understand the reasoning but that shouldn't excuse it) and that fat unsightly back end on it. Saw the Boxster get a bashing throughout the thread, but have to admit I dont hate the look of new one...
Prior to the Zed, I had a Vauxhall Astra (incoming baby, wife who likes sensible cars etc) on a 57 plate, it was the most soulless driving experience of my life. Being in it was like sitting in a children's plastic toy, everything about it was utterly awful. I joined an Astra forum to make sure I had access to knowledge and parts, what I didn't realise was that it only gave me access to people that blacked out all their windows lowered the car to the ground and classed a remapped 1.7td astra as having 'superb' performance.
