Doesn't leave very much...

Nissans in Europe are basically Renaults, which you don't want.

I would avoid BMW, their reliability is not better than average.

Possibly a Toyota SUV, maybe a RAV4?

The 2.0 auto X3 is a really nice car, Comfortable roomy handles very well and all the performance you need MPG not that good though

Hey all I’ve narrowed down my hunt for a mid sized SUV with the following requirements: - Diesel (I do 13-16k miles/year) - Automatic - Sat nav, xenon, heated seats - Approx £15k budget - ...

But for the Korean preference, that sounds like a Kia Sportage.

Designed by Peter Schreyer, who designed the Audi TT.

I have a Hyundai Tuscon (basically the same as a Sportage). DCT auto 1.7TDI.

I like it. It's done just under 60k miles in 2.5 years.

It has had its problems, many cars do. The dealer couldn't resolve a cut in power / refusal to accelerate issue as they couldn't duplicate it. Once I videoed it and the dealer sent the video to Hyundai technical the issue was resolved within 3 days and a new part was fitted.

...and the first Audi A6, which still looks timelessly modern compared with the old 'three box' design of the BMW 5 and MB E class from the same era - its same sized and powered competitors. If it wasn't for my present wheels I'd still have one.

The OP clearly set out his requirements right at the outset.

Diesel (I do 13-16k miles/year)
- Automatic
- Sat nav, xenon, heated seats
- Approx £15k budget
- Don’t like French, British, Korean or Italian brands

And you've suggested a smallish car instead of a mid sized SUIV.

He wants auto and the Sedici isn't available as an auto.

It's a Fiat and he said he doesn't want Italian.

He hasn't asked for something that'll save him a stack of money, he said he'll pay up to £15 grand.

He wants Xenon lights, heated seats and built in Sat Nav.

So, apart from that a Sedici fits the bill nicely.
