since having the gearbox upgraded i can now move into the 20-24mpg category, my longterm average is now 20.4.
City driving now gets me 19mpg and a-roads are upto 25 (24mpg @ 80mph cruise control lincoln to london and back. a1, m11)
motorway driving mpg has improved since it no longer feels the need to drop into 5th at the slightest incline.
thought id repost for any prospective owners
