On this day last year I took a flight over to England & drove my new to me 500E home. This was the first of many stops for ‘gas!’
The car has came a 
long way from the condition it was in when I bought it. It’s been an expensive but enjoyable first year of ownership – and thanks to the help on this board I’ve learned alot about the 500E. It’s a very different animal than any other w124 IMO in terms of complexity, cost of parts / repairs but also enjoyment.
  What follows is a list of the work done to date which I had prepared for the car to be valued. (For insurance renewal) It is not yet fully complete nor exhaustive but gives a flavour of what has been done to this 500E in the past year.
