Not really much point her having a supercharger if its just to pose round in anyway mate.
Plus it would be faster than your escos in certain circumstances which could be embarassing
Id go for the jag i reckon, the XK8 seems to be pretty much without any major faults as it doesnt munch through the gearbox the way the supercharged ones do.
Awesome cars to drive, and automatic suits the "executive express" feel they have.
