Buying a used BMW 3 Series - SE or M Sport?

I would like to know difference between 2004 BMW 320i SE and BMW 320i M Sport.
Which would be a better option to buy at 80,000 miles? They do not have a BMW dealer history but serviced by independent garage.

The M Sport has lower, stiffer suspension and bigger wheels with lower profile tyres. So harder ride, wheels and tyres more vulnerable to potholes, tyres more expensive to replace.
