XC60 is on the short list, for some reason I hadn't considered the V60 but seems reasonable aside from reviews picking up on the cheap plastics in the cabin.
G31 has the annoying combination of being both >£40k list price for anything but the absolute base model and >March 2017 registration, which means you get shafted with an extra £310/year tax. I know that shouldn't be a deal breaker, as what matters is the overall cost of ownership, but it does grate a little if I'm not going to be completely blown away.
F-Pace when released did get my attention, seems to be holding its value a bit too well however to make it that appealing a secondhand buy as everything on AT within 60 miles is over £31k and that's on a 2016 reg - to be honest I'd probably look for a decent offering from a broker on a brand new one.
E-Class Estate can be had cheap at the moment (£28395 brand new) and compared to most others I've looked at seems to have a decent amount of kit as standard. I just think the length of it might be a bit too much for my wife to handle, as it were.
If I was buying something without any size restriction I could see the E-class wagon potentially being the one I'd go for. Maybe just have to get the missus to sit in one and witness the active park assist!
I suspect I may end up in a situation where to get the level of interior I am craving for I'd have to pay an excessive premium and that's not something I'm prepared to do. I don't have a set budget per se so could go over £40k for something truly special but equally don't fancy paying say an extra 10 grand for a slightly prettier interior that might look dated in a few years anyway.
G31 530i M Sport is £39,392 on drivethedeal.
