Given the cars I have had over the last few years in terms of head turning I would rate in order as such:
4th place Celica GT-Four: Got the occasional glance but mostly I think people thought it was a chaved up Focus or something
3rd place 350z: "Nice Porsche" mentioned more than once, but often admired by fuel station attendants
2nd place R33: Much more attention, from a chap in Milton Keynes stopping me in a car park and asking for his photo next to it to just about every Fiesta owner wanting to race it
1st place VX220: People point, a lot, often confused. But it is relentless I cannot park in a car park or sit in traffic without someone commenting, especially with the roof off. When I had the red one a chap came up to me when I was polishing it to say how much he liked my Ferrari
