I've been looking to buy a new (well a new used car) and I finally found the one I wanted, a Punto 1.2, 51 plate, everything seemed fine until I took it on a test drive today and half way round we noticed the speedometer stopped moving and was stuck on zero then started moving after about 5mins. We asked at the garage and the man mumbled something about it was fine, it was because the lights were on all day yesterday and it was because it was electric or something but I didn't understand.
My question is, is what the man at the garage said right or is this a problem? It seems to me if the speedometer doesn't work then its not clocking miles hmm
