As you stand at rear of car looking at it on the left hand side there is a panel that opens up, did you look behind there for the service book and key ect in a big black wallet it where mine were stored on car.
Service History you can get from MB but only if recorded electronically
servicing of car at MB can be very expensive and even though low mileage some jobs have a time limit as well IE every 2 years, and in my experience not driving a car much is not good for overall operation of car. an MB service you can get a quote online my quote was £1124 with auto box oil change and mot.
You could ask on hear for and independent MB specialist near you that's recommended, there seam to be quite a lot on hear that seam to really know there stuff, would use a specialist as looking at my car not knowing an MB can cause more issues in long run.
You could save a bit of money and do easy jobs yourself, cabin filter, wipers, washers, air filter, locks, ect, Oil and oil filter parts them selves are not very expensive
2 MB dealers that have EBAY shops are
www.ebay.co.uk
www.ebaystores.co.uk
if nothing else I would check battery box for water, under floor drivers side, check cabin pollen filter drain tube, check rear spare wheel well for dampness, take out washer fluid bottle , clean out and refill with either a quality fluid or MB fluid
check spec before using any fluid in car, and if buying Patten parts like Bosch ect, use the posted parts list above to check Part numbers and if they ask always supply VIN to shop
