It’s a Premier and I can see it on Autotrader. Personally, I would go for a 2104 Premier with half that mileage. Could probably pick up a decent one in good condition up for £13k. Might even get one which still has an extended warranty. Might not be an approved used car but if it has a warranty and you do your homework it’s relatively risk free.
The trouble with a 4 year old car with 92k is that in 3 years time it probably has close to 130k miles. For me, 92k miles also means the suspension bushes, dampers, steering, wheel bearings etc are all nearing time for replacement. Of course it does depend upon how many miles you do, how long you will keep the car for and whether you are bothered by how tight a car might feel on the road.
These are good quality cars so mileage in itself isn’t such an issue. I’d want to see the full service record for the car to see what work outside of servicing has been done. Has anything else been replaced.
When I first read the OP’s post I thought it sounded expensive. Looking at available cars shows it’s priced about right from a franchised dealer which surprised me. I doubt you will get £1500 off it because in these days of internet advertising dealers tend to price quite keenly, you might get it for 14k though. What Car valuation is £14k if in excellent condition and from a dealer. Start at £13.5k with a view to paying no more than 14k perhaps. If a service is due within the next 3-6 months I’d negotiate a free service too.
I’d definitely prefer a 2 year older car with half the mileage though. Put a private plate on it and it would look like new if it was good condition.
Good luck!
