Mrs Mad Rapper (to be) has just been offered a new job with company car. She was given a choice of the following manufacturers: Audi, Mercedes, Saab, Toyota or Vauxhall. Use will be fairly frequent drives from Buckinghamshire to Northumberland, and then during the week just 10 miles to the train station and back. We want an estate, so have narrowed it down to the following: Audi A6 Avant 3.0 TDI Quattro S Line Mercedes C350 CDI Sport Estate Opinions on which of these please? Additionally, neither of us have had a company car before, so should we use up to the £450 a month they'll pay to take one of the above, or £5500 in cash she's been offered and put that towards something else?
