Hi Susan,

Wow, you're a glutton for punishment aren't you? You pretty much couldn't have picked two less reliable cars. The Discovery is best avoided. If you could afford to trade up to a third-generation model I'd say that's worth a go, as Land Rover was starting to get on top of its quality issues by then, but the old Series II is just bad news. Gearboxes go, electrics go and even the suspension can fail. I know what you mean about falling in love - it's happened to me too with old Land Rovers, but you're looking at a very high-maintenance partner there.

The Espace is a little better, but not by much. The diesel engines are very fragile - check for smoke, check for oil levels and if there are any signs of overheating, run don't walk away. Check anything with an electrical wire coming out the back of it too as it can all go wrong, although the electronic parking brake and electric windows are especially prone to wrongness. Also, keep an eye on the tyres. Espaces go through them like butter and 20,000km is about as much as you'll get out of a set.

If you really want a seven-seater that works properly, can I suggest either a Mitsubishi Pajero or Toyota Land Cruiser? Not as cool as the Discovery, but they won't let you down.

Hi Noel,

Nothing too serious to worry about it. That 2.0-litre TDCi diesel engine does suffer occasionally from cutting out unexpectedly, but it's usually just a software fault and the ECU can be easily updated by a dealer. Other than that keep an eye out for issues with the keyless entry and ignition system (a rarely-seen option anyway) and keep an eye on the cabin - creaky trim is common and apparently the seat bolsters can collapse even on surprisingly low mileage cars.

Hi Eamonn,

I'd say about €3,500. A little more if it's the D5 diesel version, but it's not the most beloved Volvo model and was unfashionable at the time because it was stuck with engines of 2.0-litre capacity and more.

Hi Gerard,

Sadly the answers are yes and yes. I always quite liked the 75 (and its sporty offshoot the MG ZT) but the sad fact is that reliability is not their strong point. 

While the 75 was probably the best built Rover ever that's not saying much and quality was always an issue. The head gasket issue is linked to the intake manifold, which warps as it ages and causes gasket leaks and failures. 

Sorry to say but it's probably best left well alone.

Hi James,

At that low mileage it should be fine. Electrical gremlins are what strike the Scenic, especially the electric windows, but also watch for problems with the cruise control, alarm, electric parking brake and even the indicators. The good news is that the engines are pretty robust and either the 1.5 or more powerful 1.9 dCi diesel engines are good choices. 

Oh, do watch for bits of the cabin coming off in your hand too...

Hi Martin,

You'd be surprised how many engines still make two with two valves per cylinder (i.e. eight valves in a four-cylinder engine) and actually, more valves are not always better. Generally speaking, an eight-valve engine has better low down torque, where as a 16-valve design allows freer flowing gas at higher engine speeds, releasing more power. However, the eight-valve engines are often more rugged and reliable and of course cheaper to produce.

Hi William,

There are three engines available in the latest Corolla, and though we assume you mean the 1.4-litre diesel, here are all the official figures for completion:

1.33-litre petrol model: 50.4mpg (5.6 litres/100km)

1.4-litre diesel model in Terra grade: 74.3mpg (3.8 litres/100km)

1.4-litre diesel model in Aura or Luna grade: 72.4mpg (3.9 litres/100km)

1.6-litre petrol with automatic gearbox: 50.4mpg (5.6 litres/100km)

Note that these figures are all official 'combined cycle' results and don't usually reflect what drivers achieve themselves.

Hi Eamonn,

MPV means Multi Purpose Vehicle. Some refer to it as a people carrier too.

HDi is a PSA (Peugeot/Citroen) brand name for diesel engines. It stands for High pressure Direct Injection.

Expert answer

Hi Noel,

No matter which engine is fitted to your Jetta, the recommendation from Volkswagen is that the belt is changed after four years if not before that. The 1.6 and 1.9 TDI engines have different intervals otherwise - every 225,000- and 130,000km respectively.

It's always a good idea to be cautious so if your car has never had a change we'd urge you to get it sorted out now.

Expert answer

Hi Amanda,

Yes it will - the new S-Max will have two down-sized engines compared to the current model. A development of the current 1.5 TDCi, as seen in the Fiesta and B-Max, probably developing around 115- to 120hp and a new three-cylinder petrol turbo 1.5-litre EcoBoost engine. Both of those should significantly bring down the running costs of the car, and we'd be very surprised if both don't sneak into Bands A1-A4 for tax.

Quite whether their day-to-day fuel economy will match up to their expected quoted figures is another thing; small engines in big cars tend not to do so well when it comes to real-world economy, but we look forward to finding out. The current S-Max is one of our favourite cars and the new one looks likely to pick up where the outgoing one is leaving off.
