Since the software updates, I am getting 25 mpg average. Before the updates is was less than 20 mpg. Thats mostly on town driving with lots of stop starts. So, that should give you an indication of the mpg you are going to see.how much higher your running and servicing costs are now please?
Also, you will want to use use Super unleaded so factor that in. The car is sluggish on standard unleaded.
