i bought a manual 316 6 months ago, 65k, 12 months mot, 12 months tax, 2 owners, 2 door, in pretty good condition, mint interior, fsh, even has the original spare tire thats never been fitted and all the original tools, etc etc, it set me back £575, so it sounds like the auto with that mileage, £400 or less, but thats with good tax n mot imo, hope that figure helps.
