If it's a decent car, which the Puma is, then it doesn't matter what's underneath !
You'd be an idiot to slate the Jag X-Type cos of it's Mondeo underpinnings, and the same applies here.
Audi TTs are a *bunch* more money than the Skoda/Seat/VW versions of the same chassis - but they aren't particularly overpriced when compared to the rest of their sector.
etc. etc. etc.
Get back to your Italian shitboxes :)
