Visited a few months ago to see a GLA as my Mercedes lease was coming to an end. When I arrived the cars that are supposed to be sanitised had another on the spot sales customer there even though I had booked. Took the car for a test drive and it had clearly been smoked in. A few months later having my service and MOT done here - I brought the car here at 8am and they didn’t open the gates for 10 minutes. Then no contact all day, I was calling from 2pm and nothing. Then I got an email to say they do not have my number and quoting a price for 2 tyre replacements - CRAZY PRICES! Replied and nothing, called HQ and nothing.. they return my call at 4pm and say to collect at 5pm.. I decided to fail the MOT, go to my own garage and then come back to get the MOT signed off.. sat here for over 30 mins waiting for my car and an email to make a payment which is not coming.. staff are RUDE, a lot of people waiting around.. RIDICULOUS!!

Appalling service from the customer service department have bought a new used car from there. Had a glow plug warning light the minute I left from Showroom. Been back from the 1st prepaid service they replaced 1glow plug than the glow plug light light came back 2 weeks later. Now asking for £120.00 Diagonstic fee to look into it. We bought 4 cars in that month.

I WAS TREATED LIKE CRAP AT MERCEDES COLLINDALE I very strongly advice not to go to this showroom and to especially avoid the sales person called Juiel Miah. This person and the showroom is the worst I’ve come across to date. Roughly around April/May I found a Mercedes 200d I was interested in purchasing Registration KO67 KLZ. Having made serval enquires about the car I was finally put through to an extremely nasty sales person of the name Juiel Miah. Over the COVID period I final came to a decision that I was interested in buying so it was put aside for me till they were able open for business on 1 June. On opening for business I made contact with Juiel Miah explaining that I was still interested in the vehicle and would he drive the car over to me to test drive as earlier planned, he said this would not be possible as the guide lines for customers viewing the car has changed due to the Covid 19 so I would need to make my way down to there Colindale showroom to view the vehicle. I then proceeded to request for video the vehicle to be sent to me in response all I was sent were a sent shoddy photo and video of the car showing the car in an extremely very dirty state seen as attached. I was further given an appointment to test drive the car on the 9 June 2020. Come the 9 June 2020 I was about to leave only to receive a flash call from Juiel Miah in which I was the one to call back. On getting through he asked me where I was and he would have to cancel my appointment as the car had a spear part missing from it and I would need to wait another hour before he could call me back. This person seemed so unconcerned, there was no effort to forewarn me a day or two days before that the car would go into any repair, I had waited a good week for the appointment in which the car should have been prepared for my viewing. I was so annoyed I sent him a WhatsApp message saying I longer wanted his attendance anymore should I continue to deal with him I will no longer purchase the car. I was so annoyed I called and requested to speak with the manager who eventually explained that due to the COVID-19 they were having difficulty with parts being delivered and they would rebook me for 13 June 2020 promising to have the car cleaned and Covid 19 ready and hopefully I would finally purchase the car. To cut a long story short come the 13th June 2020 I took a cab from place to take the test the drive of the car. After waiting a few minutes this Juiel Miah came greeted me and took me to the car, it was to my utter dismay and horror to see the car as shown in the pictures with the bird muck on the roof of the car, the car hadn’t been cleaned it was in an extremely dirty state. I must say I did take the car for a test drive which looking back now I shouldn’t never have done that but on second thoughts it’s a good thing that I did as thinking now the car hadn’t even been prepared for Covid 19. I drove the car back, I was so upset. I vehemently complained to this Juiel Miah as to why would the car be in such a disgusting condition knowing fully well that I had been waiting for so long to view the vehicle all I got from this nasty person was ‘so am I buying the car or not’ in which I replied with a very big NO. I further made complaints of my treatment to a senior staff member only for that person to take the side of Juiel Miah with no consideration of my time and cab expense I had taken and spent. So follow buyers avoid Mercedes Collindale like a plague. I will never go there again and now I’ve debeen put off from buying any Mercedes a this is my second bad experience.

Thier incompetence make me wait 3 weeks to make a key, just to copy from my soare key to a new one. After 2 weeks they lost my key, I need to wait another 6 days for them to look after my key. On top of that my new key comes without the physical key - blade. No one is there to ask for explanations, each one just send me to another one. Very poor service , contact through phone never work, staff unhelpful. So disappointed like a big brand has so low standards.
