Guys, looking at one of these for the wife and baby as an alternative to the mondeo etc.

Questions, are these any good? I see they come in different power outputs - 121, 138 ish bhp and a newerengine with 143 ish bhp.

Are these cars reliable? Is there a big difference with regards the power outputs and the way they drive Is it worth going for a higer mileage car with the newer engine?

I'm aware of the service intervals and that 75k is a big one, but are they econmical cars and how are they to run?

Any advice greatly appreciated.

They're good but there are a LOT of reported problems with the DPF (particulate filter) causing problems sometimes leading to complete engine failure. They are not suited to short trips and you must keep a very close eye on the oil level and follow the instrution manual to the letter.

Thanks for the info.

Regarding the problems, how do they compare to others like the mondeo with its injector issues and/or the passat with similar things?

Also, how would a high mileage accord compare?

cheers

Yes.

If you buy a DPF engine'd one they don't like short journeys, they do well on long stretches.

Their nice to drive though, and comfy too.. I'd go for the 143 if I went for any of them.

If you do decide on one, I can check service history/warranty etc for you smile

I've been looking at these too, seem much cheaper than the equivalent Mondeo...

Cheers fella!

Not sure what to do as the wife does short 10 mile journey's but prefers the torque from a diesel.

I have the 143hp one. It was high mileage when we bought it and it has been absolutely fine. It needed a wheel bearing for the MOT (at 125K) and that has been it. It seems to be easy on the tyres too. You need to check the oil level regularly and top it up. The engine does use a little bit of oil ( half a litre over 10K) and due to the site of the oil pick up, this can make the oil pressure light come on going round round-abouts.
It is the one of two cars that I have driven/owned that doesn't have any squeaks or rattles. The front suspension is twin wishbones and the front grips well. The rear is semi trailing arms and this is fine, but the rear will lose traction before the front if the car is unloaded. The cruise control is good and the dials are easy to read. The clutch is on the heavy side, but is not noticeable now. I am 6'2" and I fit in the car fine, with more length adjustment if I needed it.

I had heard good reviews of the Accord before I looked at the Mazda, but all the things that were said about the Honda could be said about my car.

Personally I wouldn't go diesel unless you're planning to put a lot of miles on the car.

Cheers for the info, good to know especially given i'm also 6'2".

The Petrol v Diesel debate is going to ring true here and i'm going to have to do some calculations and get the wife to drive a few petrols as well i think.

The problem with the oil is not too little, but too much. Diesel ends up in the oil due to the regeneration process of the DPF which eventually ends up with the engine revving its self to destruction on it's own oil getting into the intake.

It looks like its going to be very difficult to know the condition and history of the DPF when buying a used car and picking a good over a bad one.

The big service at 75k means i'm looking for one that has had this done along with the other regular servicing, but some cars are advertised with this work being done nearer 100k, so i'm even less sure whether the other servicing has been kept up to date etc.

Can't see the wife in a petrol as the small engines will have too little power and the big ones will be using too much fuel in traffic.

A small diesel would be better, but at a small budget (4k) and for a mazda 6 / Mondeo sized car it aint gonna happen.

I bought my wife a 2004 Mazda 6 from Ford main dealer about 6 months ago and it was a big mistake.

Firstly repairs to the diesel models are obscene. A new clutch costs over £700, the 60k service which includes setting valve clearances and a cambelt is about £900. For what is supposed to be an affordable family car this is to be quite honest rediculous.
The reason the clutch went is because the engine ran away with itself when my wife was in the car with our baby. In the heat of the moment she didn't think to dip the clutch and she stopped the car using the brakes which resulted in the clutch burning out. She was then able to stop the engine by turning off the ignition. The dealer has yet to determine the source of the engine running away.

So would I buy a diesel again? No. All modern diesels come complete with stupid parts prices and almost all have potential problems with items such as Turbos, injectors, swirl flaps etc etc.
Diesel cars are for company car drivers who don't have to pay to fix them and people buying new who are covered by comprehensive warranties. Private buyers buying outside of warranty should leave them alone. After all if you don't do 20k + a year a petrol probably makes more sense anyway when you weigh everything up.

Secondly, the Mazda6. Cheap build quality, poor corrosion resistance, and under engineered. The interior trim on the 02-07 model is a level below the Mondeo and isn't as hard wearing IMHO. You only have to watch a window going up and down and compare it to that in a Ford to see that it simply isn't as well engineered. Now that's saying something, not as well engineered as a Ford.

This is all my humble opinion though. You can make up your own mind but I simply wouldn't entertain buying one again.

Sounds like you had a bad experience there.

Just to balance that out, The build quality is fine, I have no corrosion issues, the interior trim is as you would expect for a car of this range. The windows in mine work pefectly. smile

I figured that underneath, it's probably a Mondeo/Xtype floorpan, it's got the duratorque engine as is in the Mondeo, so there is just as much chance of it going wrong as a Ford.

The only issue I had with mine (56-plate 2.0 petrol from new) was road noise/tyre roar. My previous car was a 51-plate Pastit diesel which was a far quieter ride.

Handling on the 6 was great.

Even the tip box lever went the proper way - back for up, forward for down smile

I was considering a diesl Mazda 6, but the DPF issue put me off and decided to get a petrol instead.

The savings in terms of fuel costs are cancelled out by the high chance of repairs realting to DPF issues.

The 2.0 (147 HP) petrol was ideal, but a bit out of my budget so bought a 1.8 petrol.

How do you find the car on fuel with the 1.8? Miles to a tank? and on what sort of roads?

Got a '52 136bhp estate.

Turbo went a few months back . . . but then I hadn't looked at the oil level for a while so as much my own fault as anything. Oh, and it was only then that I discovered the 3 thread's worth of turbo problems with these on Honest John. Contrary to the previous post, I've read that a litre of oil every 1k miles is possible and that seems to ring true with ours.

Mine was cheap at auction so I'm not complaining too much. But, given the choice again, I'd be in a petrol.

First car in 60-odd owned where I've bought a warranty! wink

official is 25.7/47.9/36.2

but there is no way of getting over 40mpg. On a long motorway run the best you can hope for is 37mpg but then saying that around town is around 33mpg.
I think the 2.0 (147 bhp) is a bit better on fuel
