Should I buy this 2014 Mazda CX-5?

The CX-5 is a well regarded vehicle in the trade with a good reputation for going the distance and remaining reliable. However, that’s a lot of kilometres for any vehicle.

Which means, you must approach this one purely on its individual merits. That starts with the service history. Unless you can find a complete, detailed record that proves the car has been absolutely maintained correctly, you could be taking a huge punt. You’d also want to learn as much as you can about who owned it and how it was driven. For instance, 300,000km of gentle highway running is a lot different to the same distance in city traffic or towing a trailer around.

Even then, it would want to be really cheap as you might easily find it’s getting very close to the end of its useful life. That said, a well maintained, carefully driven CX-5 can cover this sort of mileage, so maybe this one has some life left in it. Maybe.
