Vauxhall cars are just bread and butter motoring, if all you expect from a car is that it doesn't break down and it keeps you dry then Vauxhalls don't disappoint. Some people forget that most people just don't care that much about cars, a car to most people is just a tool from getting from A to B.
VX probably get a lot of Police custom because they seem willing to bend over backwards and customise the cars for the needs of the Police, price probably comes into the equation as well.
Exactly what you describe funnily also fits Ford/Citreon/Peugeot/etc..
We all know these manufacturers build hum-drum cars for bread and butter motoring (with the exception of the ST/VXR type sub-brands).
The thing Ford do well is provide a more 'connected' feel to the drive, and in the case of the Vectra-C, the gap in that department is quite noticeable..
But crucially, material quality and build quality are extrememly similar, despite peoples irrationality about it.. The styling may be poor for some people, I absolutely agree on that, but I wish people would back up claims of build quality/material quality with some actual independant evidence, becuase every review I find seems to put the Vx right on the money with the Ford (And also IMO) in everything but chassis feel, but usually this doesn't translate from anything on track.
Don't get me wrong, I am under no illusion that Vx isn't humdrum, but only in the exact same way as all the rest in it's class..
I know Vx (like VW) are now only starting to wake up to the 'more connected' chassis feel.. but the bottom line is, from A-B, despite less feedback, there is enough for the equivalent Vx to be actually marginally quicker then the equivalent Ford.. Go Figure...
(That's based on the 5th gear 1.6 Focus/Astra hire car shoot-out, the VXR Astra Top Gear lap time, and the Vectra VXR EVO track time/review).
Personally, I still think Ford are smidge better in some models then Vx, the new Fiesta would be my choice over a corsa, the Focus would get it also (until the new Astra), but I'd possibly look at an Insignia over a Mondeo (But these are very much of a muchness).. But I would never, ever in a million years describe Ford as being excellent, and Vx as being dire, that would be amazingly far from the truth.. It's just a matter of choice..
