I tried a 2008 RS6 yesterday and liked it a lot.
Are there any problems with this model?
Does it need high octane fuel?
Can you get a "spacesaver" spare wheel for it?
What sort of mpg and tank range do you get when touring?
It has a lot of electrical toys - are they reliable?
Is the 4wd effective in snow?
The cars on sale seem a bit pricey - any comments on current asking prices of over £40K?
