There was no 'dodging'... I just saw some numbers that have no context to them and just thought you'd completely missed the point, which is..
If vauxhalls where any where near as bad as people make out on here, their sales figues would be 'terrible' in comparison to their peers (which in this case is Ford/VW) As long as they are 'up there' with the competition (even if they are slightly behind ford/volkswagon), then clearly enough people think they are fine.
What I think you've done is misrepresent the statistics by not putting any context to them.
For instance, a quick google reveals the UKs 10 best sellers this year..

This shows that in the UK, the Astra is selling very well, it's 3rd in that chart, focus is 1st, corsa second, and golf 5th..
This shows me that Vx are 'competitive' in the market place, and are producing products that people are buying in similar numbers to the competition (Ford/VW), that is all..
So what are your figures showing, the Corsa/Meriva are outselling the Ford equivalent, the Astra isn't too far behind? how on earth does this provide facts that Vx are 'rubbish'...
And as for marketing costs etc, I've no idea how much any of them spend? if you have info (not that it really matters), then please share!
