Any purchase is a gamble, as things can break and need investment. If thorough visual check works out and dealer reasonable, that’s a good start.
Of course, regular maintenance helps and whether you have to do now or later, it’s an ongoing cost. If the cost of a service, tyres is going to stretch a budget, perhaps leave it for now.
If funds allow and visual check good then would have service at Mazda or trusted indie straight away. I would schedule to change gearbox oil, diff oil and coolant flush, although you may wish to do in time as part of yearly servicing, rather than straight away. These things may not be required. I guess there may not be any associated brake costs for a while. Consumables reasonably priced, good labour harder to find.
Of course, the purchaser can enjoy and still have a low mileage, low owner car if they choose to sell in future, and this may help come sale time.
I would echo the comments of the two posts above. Try and get the servicing done by the seller as part of the deal, I would hope that would be in with the selling price anyway. Negotiate for a new set of tyres, don’t let the seller fit their choice, choose your own tyre brand.
As said a service (minimum) oil/filter changes, brake check gets you on the road then you can deal with other oils and maintenance as you go.
You can get a decent set of tyres fitted for around £350, I know I’ve just had two sets fitted to my two cars for around that each. So you don’t have to be looking at spending circa £1200 to sort out any problems, well certainly not straight off. I don’t think you’ll have any abnormal costs to deal with on a car that’s had very little use over 8 years if it’s a 2018 model. Just check the infortainment screen for delamination in the corners, some go like that, the window mechanism can break, new cables needed. I think also get the battery checked out, it would have been left uncharged, you bet so could be weak but still start the car. About £70 to replace, I replaced mine not long after I bought the car, it was fine but 10 years old.
In addition to all of the above advice, I would like to know if the car has been used occasionally on a regular basis or has it just been standing, completely unused? Has it been stored outside in all weathers or garaged? Has it been standing with the handbrake applied for lengthy periods or parked in gear with the h/b off? The ECU should have a data log which shows the usage of the car but I’m not sure how you would access that, unless a Mazda dealership would be prepared to do that before purchase. Check the tyre dates on the sidewall, they could have been a year old when fitted, that would give you extra leverage with the dealer, the tyres could be coming up to ten years old so there is a potential safety issue.
Thanks for your advice and thanks to everyone else for all theirs. Great place this forum!
Looking at the MOT history, the car did 422, 339, 138 and 18 miles in the period 2022 - 2025 (full years). The overall trend is a declining annual mileage from first registration. I dont know anything about storage, usage patterns and tyre age but I’m dropping this car as I’d rather spend more upfront and get a younger car with full service history.
When I had my motorcycles, which were essentially fair weather, very low mileage Summer playthings they were always serviced by the book every year regardless of mileage. To my knowledge, modern cars usually specify a service is required every 12 months or 12,000 miles, whichever occurs first. Some items such as air filters may not need replacing but oil & oil filters, hydraulic fluids should be replaced according to the maintenance schedule. It’s also a good idea to get a car up on a lift once a year for a thorough inspection to check for rubbing cables or damage to brake pipes etc.
Why does it need a diff. oil change? I have a 2015 1.5ND with 26000 miles and full annual Mazda service history, and I have never been advised for a diff. oil change!!??
According to Mazda its a non-serviceable item unless its been submerged. Anyone who knows the MK4 well knows that both the gearbox and the differential run VERY hot. General advice from specialists is to change the differential oil annually. I’ve done mine throughout my cars ownership even though it only covers at most 3k miles each year. Its extremely easy to do yourself, especially if the car isn’t lowered, you don’t even need to jack the car up. In our MK4 facebook group alone, I’ve seen atleast two cars with failing differentials where the owner advises they’ve not known the oil to have been changed.
Oil degrades over time whether on a low or higher mileage car. As the above post, advice from the experts (someone who services these everyday) change the diff oil regularly, especially if doing motorway miles, the diffs get very warm. It cost an extra £20 (ott price) let’s say every 2/3 years to change that oil, worth it. Gear oil £40 I’d do every 3 years at least, again not a fortune. DIY prices of course, both can be done in an hour if paying someone labour costs.
It is just ‘good practice’.
Your car should have had the gear box oil changed twice by the Mazda agent so it may be worth checking that this has in fact been done.
This is such a great forum. Full of friendly and well informed advice. Makes me want to get an MX-5 even more.
It reminds me of Bimmerpost, of which I’ve been a member for many years, which has helped me to empty my wallet on many an occasion when seeking advice . The UK Off- Topic section is always good for a laugh.
I recall, while having my Mk1 Auto rebuilt a few years back, while it was ramped getting new stoppers and coilovers….may as well drop the open diff lube out and refill? No record anywhere of it being done….so it was original Hiroshima stuff over 25 years vintage and 139, 000 miles. It came out fine, no evidence of sludge on the magnet, and we put in a nice bath of lovely Castrol whatever. The oil was dark for sure….but did not appear burned or anything. Would not attempt it with a modern diff!I was a dedicated “sump & slushbox, and PAS junky” though….fresh lubes every Spring. Also ..annual brake bleed.
The diff has very little volume of oil and runs exceptionally hot…160c Mazda clearly know about this as they fit a 10p scoop near the N/S/R wheel to cool it. If you want to be requiring a new diff at 5-7yr old subject to mileage of course don’t change it lol
