2005 Volkswagen Phaeton V8 4dr Sedan (4.2L 8cyl 6A)
The Volkswagen Phaeton V8 is heavy, and large, and heavy. Did I forget to mention it's heavy? I'm not a driving enthusiast, (who would guess it from a buyer of the Phaeton?) so I wouldn't care about it's weight, the but feeling after driving 8+ hours is awful - it feels like I'm moving all 3+ tons with my own hands. Compared to my recently purchased Audi A6, which is a class lower, the A6 wins hands down (now I understand what 'fun to drive' means).
4 parking distance detectors - with this size it's a must, especially in Europe.
Make it lighter, much lighter (e.g. use aluminium like A8).
