Saw you yesterday - Lime Green, absolutelty stuuning vehicle, nearly fell out of the SLK trying to get a longer look at you - really made my day you did !!
Doesn't always have to be him in his cars though. My neighbour is Jamiroquais guitarist and has borrowed on occasions both his RS6 and his 550. Though I'm pretty sure that with the Enzo and Miura Jay would be VERY picky about who he'd let drive them....
and i think one of the passenger windows on his Miura isn't there. i remember a feature on Top Gear about the Miura once and they featured Jay Kay's car and he said he just closed the door and the whole window just fell in! (unless he has had it repaired that is.)
