Hi Peter,

To be honest, if it's just the two of you, then you don't really need to trade up to an E-Class or 5 Series sized car - a 3 Series would do you just as nicely. That said, there is definitely a slight comfort benefit from going for the bigger model, so I can understand why you might want to. 

I'm going to suggest something a little left-field for you but I think it might just work - have a look at a Lexus GS 300h. It's perhaps not as obviously economical as a BMW 520d or Mercedes E 200 CDI, but it's enormously refined and comfortable, and endlessly reliable and solidly built. It's also really nice to drive and I think the quirky elements of the styling and engineering might appeal to a former Saab driver. Have a test drive and let me know what you think.

Expert answer

Hi Brendan,

X5. Yes, it's bigger, heavier and (on paper) thirstier than the Lexus, but it's also far nicer to drive, more spacious and actually, in the real world, probably a little more frugal than the RX 450h. The Lexus' only advantages are lower motor tax and the fact that it will be more reliable long-term than the BMW, but if you buy the Beemer with a  full service history and look after it properly, you shouldn't have any major problems.

Hi Laurence,

Well, to be honest, we don't often hear of any Lexus models suffering anything in the way of major component failure. Was there some major factor, such as physical damage to the batteries, or flooding or something like that? Batteries in hybrids and electric cars are always a concern when it comes to longevity, but Toyota has 15-year-old Prius still running around and their batteries are still working fine. Lexus claims that the batteries are designed to last the life of the car, so I'm suspecting that there's some other factor at play here.

Hi Pat,

The RX 400h has CO₂ emissions of 192g/km so that puts it in Band F, which means annual road tax of €1,200. You might be better off trying to get a current-shape RX 450h, which is in Band B2 in front-wheel drive form.

Hi Cathal,

The Q3 is nice and all but the Q5 is definitely superior so perhaps think of going for a nearly-new Q5 instead of a brand new Q3? There is no official scrappage programme at the moment, but some car makers are offering self-funded scrappage deals - Opel, Nissan, Toyota and Ford among them. Audi isn’t though, so you may need to re-think your brand if you fancy a trade-in leg-up. That said, even with the tax, a Lexus is still a Lexus so you should get a decent trade-in offer.

Hi Laurence,

It varies hugely depending on the model. The closer in mechanical terms to the original Irish and European model it is, the better its value will be simply because it will be simpler and easier to maintain with locally sourced parts. 

The more esoteric and unusual the car, and basically the more parcels of parts you need to order from Japan, the lower the value will be. 

That's not necessarily a hard and fast rule though - some cars, such as the Toyota/Lexus Soarer and the Nissan Figaro, are well catered for here and in the UK with strong parts backup. Like I say - it varies wildly from model to model.

Hi Simon,

Generally speaking all three of these cars are really well built and shouldn't give you any major troubles. The BMW 2.0-litre diesel engine has some well documented and recurring issues with weakness in the turbo, but if you buy one on BMW's approved used programme, you'll get a two-year warranty that should cover you for any issues. The Diesel Particulate Filter issue on the Audi 2.0-litre TDI engine is usually related to drivers doing too low a mileage at too low a speed for the DPF to heat up sufficiently to clean itself - it's a recurring problem on any diesel car bought by someone who fundamentally doesn't understand how diesels work and are best driven.

I'd say of the three, my choice would be the last-gen C-Class. If you're looking at 2013, try and track down one of the last Edition C models - they were loaded with equipment and got an extra AMG body kit and nice wheels too. Superb to drive, cracking 2.1-litre diesel engine (if it touch noisy) and the only drawback is that they're not very spacious in the rear.

Of course, if it's reliability and reliability above all that concerns you, buy a Lexus IS 300h and you won't go wrong...

Hi Dave,

A really decent car, actually, and an interesting alternative to the likes of a BMW 3 Series or Audi A4. Lexus' quality and reliability are both utterly off-the-clock-good so there are few, if any, problems to worry about. As long as it comes with a full service history, you should have nothing to be concerned about there. It's not quite as polished an all-rounder as a 3 Series though - space in the back is surprisingly tight, the ride quality can be very firm and while the 180hp 2.2-litre diesel is punchy and economical, it's not especially refined. Still, it has one of the best-looking and best-made cabins in the business and we think it's an uncommonly handsome car too.

Hi Damien,

It's only ever going to be a rough guess where VRT is concerned, but I'd say between €2,500 and €2,800.

Hi John,

Clearly no car is utterly immune to breakdowns or component failures, but the Lexus LS 430 comes closer than probably any other. It is staggeringly reliable. We have heard tales of people buying the (older) LS 400 model from the '90s for under a grand and still finding every single electrical item working perfectly. Try that with a 7 Series or S-Class...

The Lexus is also hugely comfortable and deeply luxurious and actually better to drive than you might think. No hot hatch, obviously, but still more capable than the roly-poly reputation would have you believe.

Downsides? Colossal motor tax costs and it helps if someone else is paying for your fuel...
