How to maintain my Ford Fiesta mk5 2008 to last longer?

Op you need to calm down. It is a 2008 fiesta that is worth nothing but is driving just fine.

Who cares if there is a little rattle there and a little squeak there. It's a fiesta, not a mustang. If the car is driving OK then it is OK. Don;t be talking about replacing shocks or brakes or this, that or the other just because you have a feeling or just to be sure. Don't do anything to it until it is actually necessary to do so - and that is when the NCT tell you you need to do it.

The only thing I would ever change on my own initiative without being told by NCT is the occasional oil change, coolant and a timing belt. Everything else including tyres, the NCT will tell you if you need it. Some people here don't like that approach but it is an approach that guarantees the cheapest motoring and whether they like it or not, the vast majority of Irish cars are maintained on that kind of NCT led basis.

And you don't need those silly LED headlights. A bog standard bulb for a fiver in any car shop will do just fine.

Drive it on like a bastard until it can't pass an NCT at a reasonably cheap cost anymore and then ditch it and buy another cheap car on Donedeal for small money.

you are putting way too much thought into this. Relax a bit. If the car needs attention, it will let you know.

Ah here, will ye calm down.

You'd coudl look into the cost-benefit of 3000 mile oil changes. The saving made by, possibly, making the engine last a bit longer could be eaten up several times over by the cost of those ridiculously frequent oil changes. I hate it when people come out with this change the oil every month crap.

Every 10,000 miles is plenty. I have often let my car go 20,000miles between oil changes and I've never had a problem. realistically ,crankshaft bearings only go very rarely in small petrol engines and that is usually due to oil starvation.

Of course, some obviously blown or worn items will need replacing before the NCT like bulbs, badly worn brakes etc, but as for things like shocks, bushings, exhausts etc, they will in most cases be able to struggle on until the NCT make you change it.

As I said, a lot of people on this forum dont like the approach, but I don't think you can deny that a very large portion of the cars in ireland are maintained on a purely reactive basis like this.

Sure look at the amount of people that give out and complain that they failed on their tyres when there was debatably 1.7mm of thread left in them.

When measured in terms of economical running costs, robustness and reliability, the 2008 Fiesta will outperform that BMW hands down. That BMW will break your heart on stupid faults, expensive repairs and will drink petrol. Not to mention the crazy motor tax.

And remember, you have your fiesta and it has a good lot of new parts fitted. You'll have to buy that BMW before you go anywhere in it, and you have no idea what kind of problems may be lurking under the surface. Your fiesta has more or less proven itself. I know which car i would rather trust.
