Maybe it's some misplaced British pride, but we can't help feeling there are some cars that simply shouldn't be modified.
Not, admittedly, that this effort from German tuning house Arden is one of the worst. No scissor doors or snakeskin leather interior, at least. But that new front clip doesn't do much for the Jag's slinky lines, does it?
Slightly worryingly - you're looking at a 200mph convertible: Arden has bumped power from 510bhp to an F430 Scuderia-pummelling 540bhp courtesy of a new exhaust, with the happy consequence that it'll now top out at a nice round 200mph.
When the roof's down, quite what happens to your face at that speed remains unclear. As, presumably, does your vision.
Still, 200mph or not, we've got to put our foot down here. This modified XKR is a wrongness. Anyone want to disagree?
