Keep A8, or Brand new A4?!

[E.L.M.O]

Hey all!

I know this is a slightly silly question to ask on an 8 forum, but it has gotten me thinking more than I expected it to.

I had an interview today (all seemed to go well, its working for a travel agent who specialize in the Non profit sector) I would be doing business development and New Business.

The question has come up, if I did get the job (or any other that could see me in a similar scenario) They provide their Sales execs with brand new TDI A4s or provide the option to "opt out" and take the extra cash on your wage instead which means you have to use your own car.

Benefits of company car are
Brand new car
Insurance paid for
Road tax paid for

Or use the A8...? I didnt have the option at my last place because you didnt get the choice, you had to use your own motor, but now I have the choice Im not sure. The 8 is a great car, but its getting a little dated. If I sold it and took the company car I know I would miss it.
