As an excited new owner of 250 Sport last Wednesday (24/04/19) we went to show family and friends our MP however when going to put roof down nothing but warning alarms? After several attempts at the correct sequence and then ignition on/off to maybe reset the roof came down and we said to ourselves must be us getting it wrong ( sure we followed procedure ). Thursday (take the 2 days off work) we go off on our first outing to the coast, we set up but then roof will not go up??? Have to sleep on bottom bunk!!! I decide to leave family to go and get it checked by Mercedes (1 1/2hr drive) on Friday. Sadly our MP is still sat there. We were told it would be looked at and hopefully sorted on Monday maybe get backed to the booked site but not even looked at I find after calling around because of no update fromMercedes, sadly Tuesday evening and again no update.Staff apologize a lot but still no action!
