Vehicle is currently stuck in park. Happened when driving along, there was no smoke or noises. Got the Mrs to put it into Neutral whilst I pushed it to the side of road and was then recovered back. The transmission oil change is overdue and is more of a yellow colour and not the red/pink it should be, had a fault code which applied to low/dirty transmission oil fault and was told to start with this if repairing. Engine is running but battery does need replacing as the voltage is low and this was also a warning indication. There are some old receipts incl a service and completed recall info/updates as well as some manuals and 2 keys. Car was a cat N when I bought it, there is a Mercedes collision repair receipt with job number from 2016 which may apply to it. Bodywork in great condition. Economical and sporty.
