I'm looking for a car of up to one year old, automatic, of a similar size to my 10-year-old Vauxhall Omega or bit smaller, with a soft ride, quite good spec (ie cruise control, air conditioning etc), folding rear seats, preferably half leather, and probably a diesel engine, but I'm not averse to another petrol. I'm likely to do about 20,000 miles a year for the next three years and can spend £17,000 - £20,000.
