Bought my first car (this being the 2020 plate 70 reg A-Class PHEV premium plus 1.3L hatchback), and unfortunately the navigation system and customer aftercare was ATROCIOUS. I was back in the Merc showroom a week after I purchased the car due to the speedometer showing 70mph on the side streets and 20mph on a motorway! There was also NO sight of the mandatory accessories that were in the car. The ENGINEERS said that a full download WASNT completed on this BRAND NEW fully fitted, TOP OF THE RANGE veichle and even after them taking my car in for the day, its still NOT WORKING. When requesting an initial check up of the car (due to the navigation system failing and taking the longer routes round town) he told me to press the SOS system in the car which directs you to air ambulance, then a roadside engineer (both who said the whole situation has heightened due to the fault of the salesman). The inadequacy of the sales team is awful especially with their customer aftercare and ’support'. When the car arrived, the salesman who I dealt with didn't bother showing me any of the cars gadgets, the car wasn’t even full charged on the electric - there was no effort made when presenting the car which was very disappointing. The car is a premium plus (top of the range) meaning that all the extra features such as the cable are meant to come with the car. When questioning the salesman i dealt with, he refused to acknowledge that the accessories came with the car and stopped replying to my messages giving no response! It was only after dealing with the engineer, we pushed for the already paid for accessories. Being a loyal customer, we had foresight of purchasing another vehicle however, due to the REPETITION OF TERRIBLE experiences with the car, customer services, problematic navigation….i’m appalled! The whole experience was very troublesome, lack of support was given from the Mercedes Leicester team, there was absolutely no after care provided. The car’s navigation and speedometer is STILL NOT WORKING. I don’t recommend anyone to purchase this new vehicle, especially from the Leicester branch. Very disappointed.
