I suspect that's the right answer. Using hire cars relatively often I see the bad side of "prestige" marques quite often. The droid behind the countr hands over keys and says "we've upgraded your car" and my heart sinks. I think the low point was the BMW 520d, which was approximately as s**te as the Daewoo Matiz. Neither car had enough power to join the motorway safely and neither of them could maintain 130km/h when crossing the Apenines. My big, lardy, Ford does the journey without even droppin out of overdrive the 520 had to ascend hills in second gear. When I went to visit a neighbour I had to change down to first to climb the road leading to his house.
The Audi A4 estate thing I was given was better as far as power to weight goes, but as an estate goes it was a stupid, badly designed farce. I also object to cars where the designer thinks "ooh black is so kewl let's make it all black inside".
I agree with him, and putting a small engine into the 5-series is real insanity.
