Lovely drive home in my new 1991 500SL yesterday. I noticed the mileometer did not move. Zero'd the trip and that too remains on zero. I assume this is the usual VDO gear issue that also affects Porsches of a similar age, or is it likely to be something more simple like a fuse? It's an early type (analogue) and all dials and gauges work perfectly. I'm too honest to want to drive around without clocking up miles so want it sorted asap! Can anyone recommend who best to sort this? I note clusterrepairs.co.uk have a great reputation but not sure if they only do newer cars.
