To be honest, when we were last in the market for a car we went to both BMW and Mercedes amongst many others. We didn’t even get to taking them out on the road as we were so unimpressed with them.
In particular I remember sitting in the Merc GLA and just found it horrendously uncomfortable, to the point where i told my wife (the motability customer, and so in a worse state than me) not to bother. We did get into both the Bmw X1 and 2 Series tourer, weren’t comfortable in either of those, and to be honest weren’t impressed with the quality there either.
I just didn’t see the ‘premium’ element at that level, although i’ve no doubt it exists at the higher price points.
For us though service is of paramount importance, and if that isn’t there then look elsewhere for sure.
The service at our Hyundai dealership has been spot on, couldn’t ask for more.
