Hi Will,

We can only give you ‘bookend’ values for this one, as we don’t know the precise 3 Series model you’ve got (316i? 320d? 335i?), whether it’s a saloon, Touring, Coupe or Convertible, nor its mileage, condition or trim spec. Therefore, if you’ve got a 250,000km 316i SE saloon, then you’re going to be in the €3,600 ballpark. If you’ve got a 320i M Sport Convertible, you might be up and around €13,000.
