Can I take a used car to my own mechanic?

In one paragraph
Yes — an independent inspection is a fair thing to ask any seller for. Ring ahead, because the car needs to be somewhere a mechanic can lift it. At ONECARS, viewings at Plas Acton are by appointment, and a reservation holds the car for fourteen days, refunded in full if you cancel.
Can I take a used car to my own mechanic before I buy it?
Yes, and it is a fair thing to ask any seller for. The limits are practical rather than legal: the car has to get to the garage, somebody has to drive it there, and it must be insured before it goes on a public road. Sort those three out in the right order and the rest is straightforward.
If the car is on our forecourt, viewings are by appointment. ONECARS is at Plas Acton Garage, 282 Chester Road, Wrexham LL12 8DU, open Monday to Friday 9 to 5 and Saturday 10 to 4, with a second forecourt at Ruyton near Shrewsbury. Ring 01978 356983 and say what you would like to do, so the car and the paperwork are ready for you rather than the car being out on somebody else's test drive when you arrive.
What does an independent inspection actually look at?
A pre-purchase inspection covers the things you cannot see standing on a forecourt: the underside, suspension bushes and mountings, brake wear, tyre condition and age, the state of the fluids, and any fault codes stored in the car's computer. A mechanic with a ramp and a code reader will see things underneath a car that nobody spots in a car park.
What it will not do is predict the future. An inspection is a snapshot of one car on one day, which is why it works best read alongside the paper trail: the MOT history, the service record and the car's own spec.
How do I arrange one without losing the car to somebody else?
Reserve the car first. A reservation holds an ONECARS car for fourteen days, and within those fourteen days you can cancel for any reason and the reservation fee comes back to you in full; if you go ahead, it comes off the price instead. That gives you room to ring round garages, get a slot and read the paperwork properly, rather than deciding on the spot because you are worried the car will be gone by the weekend.
There is also no admin fee on an ONECARS car — the price shown is the price paid. So the figure you are weighing an inspection against is the real one, with nothing added at the desk.
What can I check myself before paying anybody?
Start with the MOT history, because it is free and you can do it tonight from the sofa. Anyone can check a vehicle's MOT history on GOV.UK using nothing but the registration number: each test's result, the advisories and failures, and the mileage recorded at every test.
Read it as a story rather than a scorecard. Does the mileage climb steadily year on year? Do the same advisories keep reappearing, or do they get dealt with and disappear? A car that has been looked after reads differently from one that has been patched up each spring.
Every ONECARS car page old enough to have been tested shows that MOT history on the page itself, straight from the DVSA, test by test, with the mileage at each test. The photographs and the full spec sit on the same page, so most of your homework can be done before you get in the car.
What has already been checked on an ONECARS car?
Every ONECARS car is checked on 34 points by ONEFIX, our own workshop on the same site at Plas Acton, and the list of what those 34 points are is published at how we check our cars so you can read it before you come. Where something needs doing, the car is not handed over to its buyer until ONEFIX has put it right — that is a rule built into the ONECARS system rather than a promise made at the door.
None of that replaces your own inspection, and we would not pretend it did. What it does mean is that an independent mechanic is looking at our work as well as at the car, which is a perfectly reasonable thing for a buyer to want.
Do I still need an inspection if the car comes with a warranty?
A warranty and an inspection do different jobs. Every ONECARS car comes with a free three-month warranty on the engine and gearbox, up to 2,500 miles, with any repairs carried out by ONEFIX on the same site, and longer paid cover is available. An inspection tells you what you are buying; a warranty covers you if something goes wrong afterwards.
Neither is the same thing as your legal rights, which sit underneath both — is a used car warranty the same as your legal rights? sets out where the line falls.
What if the car is being delivered rather than collected?
If the car is coming to you, the inspection happens after it arrives rather than before. A car bought from ONECARS online and delivered is a distance sale, which means you have fourteen days from delivery to change your mind and return it, so your own mechanic can look at it at home while you are still inside that window.
We deliver free within 20 miles of Plas Acton on weekdays in hourly slots, and the car is checked, valeted and fuelled before it leaves us. The detail is on our delivery page.
Is an inspection worth it on a cheaper car?
That depends less on what the car costs than on what sort of car it is. On something with a big engine and a long history — a 2006 Audi A4 RS4 Quattro at £17,995, say — an hour of a specialist's time is money well spent, because the parts on a car like that are not forgiving. On a small, simple, well-documented runabout such as a 2010 Volkswagen Polo 1.2 at £2,995, the MOT history and a long, unhurried test drive may tell you most of what you need to know.
A quick checklist before you book
- Look up the MOT history on GOV.UK yourself, free, before you spend anything.
- Read the car's own page: photographs, full spec, and the MOT history test by test.
- Reserve the car if you need time — fourteen days, cancellable for any reason, fee refunded in full.
- Ring the garage you want to use and ask what their pre-purchase check includes and how long they need the car for.
- Make sure the car is insured before anybody drives it on a public road, including the trip to the inspection.
- Book a proper test drive as well as the inspection; the two tell you different things.
Where should I read next?
Read what to check when you view a used car before you travel, then what to look for on a used car test drive and how to check a used car's MOT history. If you would rather just ask a person, everything on the forecourt is at used cars and we are at contact or on 01978 356983.
