Actually, my GTI's speedometer shows lower speed than the one from my GPS. At 100mph, GPS says 103. The speed limiter kicks in at a pathetic 122mph (125mph on the GPS). First car I ever owned that indicates less speed...
Yeah, if I lived in Deutschland I wouldn't care if my speedo was off.
Kaiserslautern? when I visit the family in Kempton (Bavaria) I usually pick up the BMW rental car from Sixt in Aschaffenburg. Hit the A3 then the A7 south doing 250km/h (in a 5 Series) the little 3 series barely does 200km/h. Anyway, I digress...
