Welcome to the forum.


I bought used 800 miles on it then 400 miles to drive it home. 48mpg on the run home. I am sure I could get better but I was in a hurry.
Thats seems a strange mileage 800 either the first stupid owner bought the wrong car or it wasn't as good as he thought after driving it for 800 miles.
Fuel con is a sore point with these, the MFD will show a higher mpg but the only true average is tank it, use the tank and tank it again the calculate.

If you were doing a 400 mile trip back from the dealer then it would be hot all the time, short runing makes it drop.
The black roof ariel is for the the sat nav the phone kit you have to buy as another extra I think?
