The GLA is the Mercedes-Benz equivalent of the BMW X1, Range Rover Evoque and Audi Q3, a compact SUV designed to blend the practicality of a hatch with the option of four wheel drive. What's surprising is why, given the popularity of smaller 4x4s among premium car buyers, it has taken so long for the GLA to arrive.

It's no surprise to learn that it's based on the Mercedes-Benz A-Class. It uses the same platform and there are clearly big similarities in the styling, both inside and out. Despite being an SUV, it's not as big as you'd expect, in fact sitting behind the wheel it's a bit like a jacked-up A-Class - the driving position isn't overly elevated.

It does come with raised ground clearance and a more rugged appearance as we've come to expect from this style of SUV. As with the competition there are both two and four-wheel drive versions available but most people will opt for the standard two-wheel drive 200d - like the A-Class it's a front-wheel drive layout.

The engine line-up echoes the A-Class too, so there's a 200d and 220d 4Matic which are both powered by the familiar 2.1-litre diesel. It's a decent engine but not the most refined around and when combined with the 7G-DCT automatic gearbox it's a fairly lacklustre combination if you want performance. If you don't need diesel, there's a GLA 200 which is actually powered by a 1.6-litre petrol engine.

The GLA is better suited to a more laid back driving style and it's the excellent ride quality that really shines through, especially with the standard SE suspension. It's quiet and comfortable at motorway speeds and good over long distances. The interior quality is top notch too so although the basic design is starting to look a little dated now - the stereo controls in particular - the quality of the finish is very good.

What's the best used, premium SUV?
"I'm after a used, premium SUV. It needs to be automatic, of decent spec and petrol. I have £20,000 - £25,000 to spend and am looking at the Jaguar E-Pace, Mercedes-Benz GLA, Volvo XC40 and BMW X1. I'd welcome your thoughts, tips, suggestions and recommendations!"
The XC40 is the best compact SUV on sale right now. It was named the Honest John Car of the Year in 2019 and has been a huge success story for Volvo: For the latest Volvo XC40 deals, see:

Why do I lose my No Claims Bonus if I lose my Motability entitlement?
"I've recently been awarded the new P1P on the Motability scheme (no VAT) and have put a deposit on a new Mercedes-Benz GLA. After three years I'll be re assessed for my disability. If I lose my Motability entitlement, my full No Claims Bonus will not be honoured and I'll have to start again with no NCB. Is this correct? Apparently when you buy a car on the Motability scheme it comes with RSA insurance included."
Technically the car is owned and operated by RSA with insurance you have not paid for. As such, you cannot pass your no claims entitlement on to them. Contact them and request they make note of your previous history. It's becoming less common that proof of no claims is requested because insurers already have the details on their database. If you lose your Motability entitlement, you can still request your claims history from RSA. As long as you can prove that you've made no claims, the new insurer should then credit your full NCB.

My daughter hit a car at 5mph and the driver is claiming whiplash - can we do anything about this?
"My 22-year-old daughter was second in line at a local roundabout in rush hour traffic. The Mercedes-Benz GLA in front went, but then slammed on his brakes as he saw a car coming from the right on the roundabout. My daughter tapped his car at less than 5mph, she has a slight bend in her front number plate and the Mercedes-Benz has a foot-long horizontal scratch on the plastic plate below the bumper. I spoke to the owner and offered to pay for the replacement part, as well as £200 for the inconvenience, because my daughter only has three years No Claims that she will lose. However, he's claiming whiplash and went to the doctors. He's insisting on putting a formal claim in ‘as the right and proper thing to do’. Is there anything we can do? I have spoken with the claims team of our insurer, Hastings, and they have the full details."
If you feel this is fraudulent, then report it to the ABI (, City of London Police ( and the IFB ( This is where dash cameras are great, so it's worth investing in one. Ultimately, your daughter should have been paying attention and has caused damage to the other party's car though. Don't just assume he doesn't have a real injury.

My Mercedes-Benz has constant DPF issues that aren't due to my driving - what should I do?
"I brought a brand new Mercedes-Benz GLA 220d last September. Within three months of ownership my engine management light came on and the cars power was restricted. The earliest Mercedes-Benz could book me in was three months later. It turns out the problem was a blocked DPF. Since then, I've taken it back at least four times with a blocked DPF. I use the motorway everyday for work commuting and really don't do any city driving so I cannot understand what the issue is. Mercedes-Benz seems to just ignore me and blame it on my driving. I think the whole DPF needs replacing, maybe due to the long initial wait and me driving with a blocked DPF for three months."
Given your type of driving, this is a fundamental fault and you can insist that the DPF is replaced. If they refuse, warn them in writing that you will take the car elsewhere to a specialist and will use Small Claims to recover all costs from them.
