Hi Sean,

As far as the gearbox is concerned, more is always better, so a six-speeder should help keep your fuel consumption down a bit, especially if you do lots of cruising in top gear. 

As for engines, the 100hp one you refer to is a 1.6 petrol, while the 130hp unit is a 1.9 diesel. Obviously the diesel will be more economical, as the 1.6 struggles with the weight of the Passat and also suffers from problems with its driveshafts. 

Buy carefully though, as Passats of that age have often been abused by careless owners. There's plenty about however, so you can afford to be picky.

Hi Gary,

The surprising answer is, kinda, yes. If you're talking about the first and second generation Puntos, they are actually surprisingly robust. As with any Italian cars, watch all the electrical items like a hawk, but these cars pre-date the massive explosion in in-car gadgetry, so there are fewer things to go wrong. Engines, especially the 1.2 FIRE, are almost unburstable (just make sure the timing belt is changed regularly) and the bodies are strong and not prone to rust.

Hi Dawn,

The problem here is that you need space for three child seats across the back, and it's getting harder and harder to find a car that can accommodate that. The Qashqai is a fab car, no doubt, but yes, unless it's the 1.5 dCi diesel model you're talking about, they can indeed be hard on petrol. Besides, it will also fall down on the three-across-the-back test. The Xsara Picasso should be able to manage three across though, so is the best suggestion out of the ones you've been looking at, but here's another possibility: if you're looking for space on a budget, try going for a van-based MPV such as a Citroen Berlingo or Renault Kangoo. They're surprisingly nice to drive, have masses of space both in the back and boot, and both can be found with 1.4-litre petrol or 1.5- or 1.6-litre diesel engines so tax and, generally, fuel economy shouldn't be an issue. Also, being van-based, they're often more reliable and ruggedly built than their car cousins.

Hi Sophie,

It's a bit tricky to say. There's no question that the 2002-2012 Range Rover was a massive improvement over its dreadful predecessor when it came to reliability and solidity but there are legions of potential problems - everything from minor electrical niggles to full-on major component failure. Fragile areas seem to be the gearbox (perennially a Land Rover weak spot) and the air suspension. The engines and bodies are solid as rocks though. Make utterly sure there's a full LR service history.

Hi Darren,

There are very few cons, and mostly pros. The first thing to check for is a full service history, because without that, it’s just not worth looking at. Modern diesel engines need careful servicing and attention to stay reliable, so make certain this one has been cared for. The only cons really are on the inside where the cabin can get very rattly and squeaky, and sadly there’s not a lot you can do to fix that. The rest is all good, though — the Kia cee'd is reliable, nice to drive, roomy and comfortable.

Hi Anthony,

Right, I've had a long, hard think about this. You've not specified which type of car you're particularly looking for, so if you're after a seven-seat MPV or some kind of 4x4; sorry, I haven't even considered that. 

Oddly, I've also discounted diesel as, at that price level, and with the likely age range, you're looking at older tech engines that didn't have as clear a consumption advantage over their petrol brethren.

You've said cheapest and then specified a price, which suggests to me you mean cheapest to run, which really means reliable and with low tax.

So my best recommendation to you is to track down a 2000-2001 Honda Civic 1.4. Built like a bank vault, spacious and good to drive, economical and the 1.4 capacity means you won't get taken to the cleaners every time you need a new tax disc. Plenty around and most will be within your price range.

What do you think?

Hi Mark,

The most common fault with that generation Clio was with the bonnet catch that could fail and allow the bonnet to fly open when driving! Worrying that, and it never triggered a full recall, although Renault did offer to inspect and repair cars for free - make sure the one you're looking at has had that done. Engines are pretty solid, but watch for electrical issues with the windows, the CD player and the engine immobiliser. There are reports of cold starting problems, usually because of a faulty air pressure sensor and the cable-operated gear shift can give problems too. If you have difficulty selecting a gear, then the gearbox is on its way out. Cabin trim is pretty fragile and you need to watch for problems with the brake servos and front suspension arms.

Hi Martin,

The Mazda3 changed generations in 2009, but I'm assuming it's the 2003-2009 version you have. Two diesel engines were offered, a 1.6 and a 2.0. Obviously the 1.6 is the more common. The recommended change interval on that car's timing belt is every 240,000km or ever 10 years, whichever comes first. For reference, the 2.0-litre diesel version has to have its timing belt changed every 120,000km regardless of time.

Expert answer

Hi Michael,

Many thanks for the compliment. You’re right on the trade-in aspect, although that does seem to be shifting now in the wake of the diesel issue, especially in urban areas. As for the servicing aspect, it’s a tough one for us to look at in a comparison sense, as all garages are different, have different charges and servicing is not a constant. All cars will need to be serviced differently, according to how they are driven.

We have done some diesel versus petrol comparison work in the past though. Have a look here.

Expert answer

Hi Austin,

You didn't specify the engine so here are the possibilities:

1.6 petrol 100hp: has a timing belt, to be changed every 90,000km or six years

1.8 petrol 122hp/110hp or 118hp dual fuel: same as above

1.9 diesel 120hp: has a timing belt, to be changed every 120,000km or six years

1.9 diesel 150hp: has a timing belt, to be changed every 100,000km or ten years

2.0 diesel 100hp: has a timing chain

2.0 turbo petrol 175hp: has a timing chain

2.2 diesel 125hp/117hp: has a timing chain

2.2 petrol: has a timing chain

There were larger engines again in the Vectra, but we doubt you have one of those as they are very rare.
