Hi Michael,

Insignias are quite well built (they are German, after all), but seem to be prone to electrical gremlins. Check to make sure that all the buttons and switches work as they should and if anything doesn't, walk away. It's not unusual for the alarm to start sounding for no apparent reason, so be aware of that. Early models also had suspect boot seals that could let in rain, so have a careful check in the boot for any signs of dampness.

Hi George,

By and large, if you’ve got a Volkswagen on a list, then it’s going to be the most reliable, and the Caddy is hugely spacious inside too. However, most vans are generally very reliable (simply because a van that’s off the road isn’t earning money), so as long as you’re buying carefully and with a full and complete service history, you should be fine with any of those listed.

Hi F D,

As a general rule of thumb, torque is important for acceleration and power is what determines the top speed of a car (all other things, like aerodynamics, etc. being equal). In the case of your car, it has no turbocharger so its power and torque are produced quite high up the rev range. To improve overtaking, make sure you select a low gear early in the manoeuvre and get up to speed before you are alongside the car you're overtaking so you have less time 'exposed to danger'.

In terms of replacing the car with one with more oomph it sounds to me like you'd enjoy something turbocharged. Opel does a turbocharged version of that engine.

Hi Amy,

It sounds like there are a few things wrong here. If the engine management light is on then the garage really needs to plug the car into a diagnostic machine to find out exactly what it is. A mechanic can't just guess. It needs to be sorted sooner rather than later.

If your coolant was gone then the engine would seize up and stop running. You should get plenty of warning of that with the coolant temperature gauge or warning light. If it's not blowing hot air (assuming the engine is warmed up properly, as that's where the heat comes from) then it sounds like an issue with either the thermostat or the heat exchanger.

Overall, I think you need to take the car to a different mechanic and go through all these issues with them.

Best of luck.

Wow, how much detail do you want? Here goes...

Saab 92 - the first Saab on sale. Two-stroke engine made it a bit impractical.

Saab 96 - like a 92 that real people could drive. Sweet V4 engine. Lots of rallying success.

Saab 99 - the first truly modern 'big chin' Saab. Gorgeous outside and in and with tearaway turbo engine. Fab.

Saab 900 - a highly developed 99, stayed in production for ever. Lovely convertible version.

Saab 9000 - some say it's not a proper Saab as it shared a platform with Fiat/Alfa/Lancia. Ignore them, as it's lovely, big, comfy and solidly built.

Saab 9-3 - the first General Motors Saab. Opel Vectra-based. Lovely cabin but flaccid chassis.

Saab 9-5 - bigger Saab but also Vectra-based. Better than you'd think but major reliability issues.

Saab 9-3 - second-gen 9-3 was based on the 2002 Vectra but not actually much better. Handsome estate version though.

Saab 9-5 - massive second-gen 9-5 was based on the Opel Insignia, really rather good and, sadly, the last car Saab ever made.

Hi Peter,

Electrical problems seem to be the big issue. Make sure that everything, absolutely everything works properly. Alarms can go on the fritz too, going off for no reason. Clutches, diesel particulate filters and boot water seals can also go, so keep an eye out for those.

Hope that helps

Hi Francis,

Can I suggest then chopping it in for another Hyundai, this time an i40 Tourer? It's massively spacious so you won't (aside from the seat height) feel like you're trading down. It's also very comfy and, with your long-haul runs and high-ish mileage in mind, hugely economical. Drive the 1.7 115hp CRDi version gently and you should top 60mpg. 

If you don't fancy another Hyundai, then picking a similar estate from the Ford Mondeo, Opel Insignia, Volkswagen Passat or Peugeot 508 ranges should do the job just as well.

Hi Stephen,

Yes, they're pretty good actually. Mechanically, just keep an eye on the usual diesel particulate filter and make sure that the clutch engages and disengages cleanly and easily. The only other worry is over electrics. There were repeated wiring loom problems with early cars, so if any that you're looking at display even the slightest electrical gremlin, walk away.

Hope that helps

Hi Feena,

If you need actual space for seven full-sized adults (as opposed to jump seats for occasional use by small kids) then pretty much all of the medium-sized SUVs, such as the Opel Zafira, Peugeot 5008, Citroen C4 Picasso and Ford C-Max are out of the question. They're simply not big enough. You'll need, therefore, to trade up to a proper, full-size SUV and in that category there's simply nothing better than a Ford Galaxy. There's real space in the third row even for big people and while the 2.0-litre 140hp diesel engine is a bit juicy on tax (Band C) it's pretty good on overall fuel economy .

They're robustly made too, and while the Galaxy isn't on Ford's official Irish price list any more, a quick ring around the dealer network should easily turn up either a dealer demo model or a very young used car.

Hi F D,

The 100hp Astra was never the quickest car in the world at the best of times, and much here will depend on exactly when and at what rpm you’re trying to change gears and accelerate. I think it’s a bit early to start talking about power upgrades or changing the engine management system — your best bet is to get the car into a garage and have the engine checked out for any issues. When was the last time you had it serviced, for example?
