I'd like a new diesel car for 2026 delivery...
I have a 2.0-litre diesel Mondeo. It's a nice motor with no problems, but I need to change it soon. I will order in September this year for January 2026. Can you list five options for me? Similar size car with a diesel engine, please.

Hi Fergal,
That's actually becoming a bit of a challenge as regular cars such as the Mondeo have fallen out of favour with buyers, so the carmakers are slowly doing away with them. At the same time, demand for diesel engines is waning. Nonetheless, here are a few possibilities:
- Audi A5 'Saloon' (it's actually a five-door hatch)
- Mercedes-Benz C-Class saloon
- Skoda Superb (another hatchback and the closest match to the Mondeo today)
That's pretty much it. A leftfield alternative could be the Peugeot 508 SW, which is the estate model. It can be had with a diesel engine still, but the five-door 508 fastback cannot. We reckon it looks stunning.
How do these strike you?
What's up with my Mercedes C-Class?
The collision avoidance system and traction control keep switching off on my 2016 Mercedes-Benz C-Class. When I switch off the engine and restart everything is ok again for approx 20km when they act up again. Any ideas?

Hi Charles,
Sounds to us as if one of the system's many sensors is not working properly, causing the system to shut off. We recommend bringing the car into a Mercedes dealer to have it looked at. It should still be under warranty so hopefully it won't cost you anything.
Let us know what it turns out to be.
Worth using fuel additives in my Skoda?
Hi,
I have a 1.6 TDI Greenline 2012 Skoda Superb with 70k km up. An injector recently had to be replaced. I don't know why, possibly because the car is unused for a few months each year. Is there any benefit in using a fuel additive to prevent further damage and, if so, which?
I also have a 2.0-litre petrol turbocharged Mercedes-Benz C-Class (245hp) of much more recent vintage. Is there a benefit of using a fuel additive from early in a car's life? Is there any evidence that these products. work?
Many thanks,
Philip

Hi Philip,
The short answer is that there are some benefits to using additives, but they’re not a miracle cure. Some additives, such as Redex, STP, or Dipetane, can apparently help to reduce the build-up of carbonised particles of soot and burned fuel on the insides of your engine, which can lead to improvements in reliability, fuel economy and emissions.
That said, there’s little here that’s scientifically proven. The benefits of additives tend to be more word-of-mouth than provable fact, but there’s certainly no harm in using them and if you notice a benefit, well that’s all to the good.
I would suggest that you’re better off sticking to a strict service regimen, using original parts and a qualified technical, than relying on additives though. And of course, as you already know, diesels need to be driven regularly to stay in good condition.
I'd like a sporty car from 142-152...
Hi guys,
I currently drive a late 2012 Audi A3 (new model three-door 2.0 TDI). It's a great car, but I'm in a position to upgrade and I want something that has a bit more oomph on the road and is a bit bigger. I have a good 45-minute commute each way to work and I have friends and family all over the country so I need a diesel for all the miles I'm covering.
I'm looking at purchasing second hand, probably cars registered from 142 - 152. I'd love a BMW 420d M Sport, but they can be pricey and I have heard from a few people that used BMWs can be far from reliable. I have considered sticking with Audi, but I have found that Audi cars from this time period (A4/A5) are a bit underpowered and poorly equipped for the money. Is there anything you can recommend? I find myself only looking at German manufacturers, but I can get over badge snobbery if I found something I really liked.
Thanks guys

Hi Pearse,
Would you consider a Lexus? A hybrid engined IS 300h saloon looks good, is good to drive, isn’t German, is frugal and will be so reliable you can pass it onto your grandkids.
Alternatively, a BMW 420d Coupe makes a great buy, and they’re not THAT bad on the reliability front, but it’s a good idea to buy one from a BMW main dealer, as it will come with a very comprehensive two-year warranty.
Well worth looking at a Mercedes C-Class C 220 d coupe too — not as slick looking as the BMW, but with great quality and a really lovely chassis. The Volkswagen CC (four-door coupe on a Passat chassis) is also well worth a look, and what about a Jaguar XF 2.2 diesel, which is a saloon, but looks slinky enough to be a coupe?
Can you check this Mercedes for me?
Mercedes-Benz C-Class CDI Sport: reg no 12 D XXXX: is this car ok to buy from a private sale?

Hi Nora,
I'm afraid we can't do that check for you, as there's a small fee. Your best bet is to go directly to Cartell.ie and pay for a full history and finance check. It's not expensive and a great investment. We do it ourselves when buying used cars.
What's the best coupe for under €50k?
Best coupe available for under €50k in Ireland? Audi A5 2.0 TDI S line 190hp? BMW 4 Series? Other?
Thanks!

Hi Brad,
As ever, the answer is: it depends where your priorities lie…
The A5 is indeed a cracking car. Not the sharpest to drive, perhaps, but gorgeous to look at and practical inside. That goes equally for the Mercedes-Benz C-Class Coupe, but the BMW 4 Series is the best one to drive. Don’t forget the 2 Series Coupe either, which is more fun than any of the above. Actually, though, the best one of the lot is probably the Toyota GT86. Not as premium or as big as the others, perhaps, but more fun to drive than any of them. Here are a few of our reviews to help you decide:
Audi S3 or Mercedes C-Class - both cabriolets?
Hi,
Could I ask you to compare the Audi S3 Cabriolet with the Mercedes-Benz C-Class Cabriolet for about the same money? Both are quality cars. The Mercedes possibly more polished and stylish. The Audi has four-wheel drive, is faster and smaller.
Thank you, Philip

Hi Philip,
You’ve pretty much summed it up there. I guess it depends where your priorities lie – performance or comfort. There’s no doubting the sheer thrust of the 300hp Audi, but I would suggest that if it’s performance you crave, skip the Cabriolet and buy the Saloon, which is much better to drive. If it’s the open top that you fancy, then go for the Mercedes, forget about performance (although the Merc is hardly a slouch in that regard) and instead revel in the comfort.

Which premium coupe will I go for?
Hi guys,
Would really like a nice coupe. Trying to decide between Audi A5, BMW 3 Series or Mercedes-Benz C-Class.
Any thoughts?

Hi Joe,
Each has its own charms, really. The 3 Series is an obvious choice – handsome, practical and really good to drive, but you might find the ride a bit too rough at times. The A5 is hugely handsome, has a terrific interior but it’s a bit dull from behind the wheel. I’d go for the C-Class. Not quite as obviously handsome as the other two, but it’s terrific to drive, and really well put together.
Which cars are best for comfort?
Hi,
Can you tell me which SUVs offer a driver's/seating position most like a standard car's? My wife and I currently both use her Opel Zafira and I find the seating position very upright and uncomfortable as the seats will not move back far enough. Effectively it means I have to lift my feet completely to operate the pedals instead of just pivoting on my heels as with a more reclined position. I have recently had a hip replaced and the other one is painful if I drive any reasonable distance.
We test drove a secondhand C-Class Estate and I wanted to buy it but she finds the seating position very cramped (in particular did not like the large console between the seats). We sat in a Honda CR-V after and she much preferred the space and lack of clutter between the seats but I found the seating position uncomfortable. Essentially we are looking for something that has the high ceiling, big windscreen and lack of clutter of most SUVs/MPVs, but with a seating position that gives good enough leg room for somebody over six-foot like me to pivot my feet on my heels rather than having to lift them to operate the pedals. Maybe we need two cars, which is a waste given we are city dwellers and do very small annual mileage between us.
Thanks
Kevin

Hi Kevin,
That’s almost an impossible question for me to answer I’m afraid as, as you’ve pointed out, a car that many might consider comfortable and pleasant (the Honda CR-V) is uncomfortable for you. Mind you, you’re right about the C-Class Estate being small inside – it was never the biggest car around.
Is 1.6 diesel enough for new Mercedes C-Class?
The new C-Class Mercedes has option of a 1.6 diesel engine with 115hp. Is that a little weak for a big car? What do you think?

Expert answer
Hi Oliver,
Actually, it's really good. True, not the fastest car in history, but peppier than you'd expect, smooth and very economical. Actually suits the car rather well, but if you're doing low mileage, have a look at a C 180 petrol model, which uses a 1.6 turbo petrol engine. Well worth checking out.
