And stop fobbing people off with $hite cars.
I had a Vauxhall Zafira as a hire car last week, drove it 400 miles.
What a truly dreadful car!
The real shame is that the car bits are pretty good... chassis is reasonable, with little roll in corners and decent grip, well judged against ride comfort. I think it could do with slightly softer compression damping and slower rebound, but then again there was only me in the car - laden it would probably be fine.
But it's the cabin where it all goes disasterously wrong. Leave aside the horrible quality of some of the bits of trim... Why have they changed the way indicator and wiper stalks work?! It wasn't broke before, but now it is! The handbrake is stupid (aircraft throttle style) - you get used to that, but putting the cupholder in the middle of it so you can't use the handbrake when there's something in the cupholder?! Then the armrest that either covers up the handbrake (and cupholder) or you bash your elbow against when using the handbrake... And the noise. My head has just about stopped ringing (to be fair, wind and road noise weren't too bad... it was just the god-awful diseasel engine that never sounded anything less than John Deere). The seats are flat and unsupportive, shiny bits of trim reflect streetlamps in the windscreen (fireflies!), etc, etc, etc. Most of this stuff that's wrong is designed in - it cost them money to come up with the idioticator stalks, silly handbrake, etc when it's all so unecessary.
The scandalous part is that a more comfortable, more economical, quieter, smoother, higher-specced, more reliable, more spacious honda accord tourer diesel was less than £1000 more to buy new.
I'm not sure that it's Hyundai and Kia that GM have to fear... it's themselves.
