My 22-plate Advance has just had its first service.
It's always hard to tell, and I could be deluding myself, but I would say there have been a couple of changes in behaviour. The main one is that if I stop the car, park, and wait for a few minutes without turned the power off, the car no longer prompts me to turn it off but is instead happy to sit for ten minutes with the power on. Is this likely, or am I mis-remembering?
