They do, but only in comparison to the 10.25 screens. However, have the same functionality on the media screen and have lots more functionality on the instruments screen than two analogue dials.The 7" screens look absolute naff IMO.
I am getting my car (B180 Sport Auto) on Motability this month. I had it narrowed down to 3 cars as I require a higher seating position for entry/exit. Volvo XC40 R design manual, BMW 218i SE Active Tourer Manual or the B class. All three had deals on them from various dealerships around the country (Motability Deals | Motability Cashback Offers | MotaClarity).
The BMW, Volvo and the Merc all had deals where the advanced payment of £99, £799 and £999 respectively would be covered by the dealer. At the time, the BMW dealer would also give £250 cashback upon collection of the car (since price change in January now £500 cashback). I could have gone with the XC40 which has two huge screens or the BMW which had two smaller screens. The Volvo you have to do EVERYTHING through the centre screen. My sister has one and I find it a pain in the arse. The BMW is at the end of its life-cycle and a new one comes out later this year.
For me to move up to the two big screens it would currently increase that advanced payment from zero to £1,949 - £600 dealer contribution of £600, so £1,349. I couldn't justify that price difference as I have a wife and 12 year-old son who suffer from an ultra-rare genetic disease and we have to live very, very frugally as we have to regularly travel from Edinburgh to London (GOSH and Royal Free) for medical appointments.
What we do get with the B Class is the seemingly great, frugal engine, high seating position, heated seats, movable rear bench, automatic gearbox, lots of safety equipment and the ability to do everything without moving hands from the steering wheel enhancing that safety. As the B Class is an A Class that's eaten all the bacon rolls and still only weighs about 50kg more than the A class, I am assuming I will get close to the same mpg as the figures mentioned in this forum.
In 3 years time, we will have a look around again.
