Hi All.After a 3 week delay(DVLA cockup)I finally collected my 2yr old 1.6Tekna. Well pleased, drives like a dream with enough power for what I need. My first trip was a holiday driving from near Glasgow down to the Norfolk Broads, Gt Yarmouth and various detours to visit relatives. I covered over 1000 miles(Glad it only had 4k on the clock to start) According to the computer I averaged 57.4 mpg which surprised me. How accurate are the computer readings?
