Look at the state of that.
Is it too much to ask for someone to just own a "nice older car" these days without thinking they know better than the original designers? That one looks like it has been randomly attacked by the owner and his can of gloss black Halfords paint.
And that's what we're trying to show, you can't really get a luxuary car that will be low mileage, mint condition, looks ace and will look great on thwe drive for £6k (especially a Range Rover which is what this is all about really)... what you're seeing there is the lowest level of luxury unfortunatly, hence the overwhelming response of, probably not a good idea. But if the OP is deffo going that way this is the kind of 4x4 he'll be looking at imho. A saloon will be a better choice really, Jags, Mercs and BMW's and Lexus seems to be where the money should go...
For me, it's why I didn't try and buy a 6k luxury car, because it's borderline impossible, it may look like you can but nahhhh for me, you up your budget OR you downgrade your expection. My main things when I buy a car are:
1). Do I really want that car and I'm not buying it purely to show off i.e. it's what I WANT.
2). Mint body work is essential and invariably that comes with low mileage so these two are usually linked unless it's been someones pride and joy, but I've learnt lessons of higher mileage cars now.
3). Don't go to the bottom of the price bracket for that particular car i.e. I was looking at Bentely Continentals... and that would mean sacrifices... on a Bentley... I mean... I had to slap myself in the face
4). Know exactly what the reliability of that particular car is like, what are it's pitfalls and how much as those pitfalls. Think of Tax, Insurance and running costs and ensure you're fine with that.
5). Engine bay and tyres. Sound stupid, but does it look clean and maintained or a dust fest in the engine? Has someone bothered to keep it clean or if it's dusty as hell means it's never opened? Are the tyres cheap? If so I walk away, simple as that, as it's been maintained by A). Someone who is retarded or B). Someone who can't afford decent tyres. Same outcome, early death.
They're my kinda of questions, hence, I'd be lowering expectations for a £6k Luxury car. Luxuary cars are generally around the £60k mark, dependant on your meaning on luxuary and that invariably brings Luxury maintenance costs
I still think personally the Jag XF would be as good as I'd be expecting in this price bracket... I mean it's a Jag, all the bits... for less than the price of a Ford KA!
