Thanks for the advice. I get the drive next month and have the car for around 6 hours thanks to the nice people in Chester, which is more than 2 Audi dealers niether have been in touch with me even though I wanted to look at buying one.
After reading what everyone says about it I think I will no doubt buy the Lexus. It will get a good run on the twisty roads in Cheshire so I can have an idea what it is like to drive into work. The other killer point for me was I saw a VW passat and A4 next to each other whilst in jam on M6 this morning and they look identical. I know they have the same floor plan but the could have done something to chang it apart for the badge!
Me thinks a Lexus will end up on my drive soon :D
