It's an odd one really, the attention and compliments thing. I always used to get appreciative comments with the Jaguars (XF and XK) I have had, but never the BMW's (though I haven't had the Z4 long). I had a couple with the Audi A4 convertible and some with the Audi TT, but the one car that always drew massive attention, (even phone numbers) was the TVR Tasmin I had in my 30's.
