I bought my wife a 3.0 petrol sport one of these not long ago and I like it. It’s a lot of car for the cash, it’s a quick and effortless cruiser, takes a lot of luggage and has been OK so far.
Ride is hard and hers is the hardest option by far but frankly it’s fine and it goes round corners without rolling too much which is nice.
It’s not cheap on fuel but we do bugger all miles so it’s OK. Key things are matching tyres to save the transfer box ours are 19’s and not inexpensive but its a big costly car so there’s that. Also rear springs rust and break on all models so check those too. Independent service on day one cost me 250 for transfer box oil, oil change & filters + adding an aux in lead. Full check and diagnostic showed no faults. I’m told the later M series diesel is the one to have not the N which is shit as has been said or buy a petrol six which is a lovely engine TBH. Also has a very good and super loud sound system
