I need to buy a second hand automatic car. It needs to be capable of holding a 3/4 size Double bass, and a full size cello (occasionally) + 2 teenage children. Ideally quite economical to run.

Wife likes Prius (but not sure if we can squeeze everything in).

I had been thinking of Mondeo Estate. We both like Toyota Verso but seems out of budget. Should we consider high mileage cars? Budget is £6000.
