running costs

Hi,

I am considering buying a 2008 BMW 316i se petrol. Any idea roughly what the mpg of this car might be (the dealer told me 49mpg)? I've trawled the net with not much luck. I do approx 13.5k miles per year, would I be better off with a diesel? Your advice is appreciated.

Thanks Gavin (Tipperary)

I am considering buying a used 1998 Toyota Corolla 1.3 with 163,000 miles on the clock. I expect to do 15,000 miles per year. Over next five years what wear and tear repairs might i expect?
