I'm also looking for a 7.5 estate, but probably a MY19 if I can find one well priced. Ideally I want DCC and 18" wheels, but what I've read the ride quality on the 18's is reasonable without the DCC, so perhaps I can live without it. I'd also like heated windscreen and the pano roof, but they seem very rare, if not impossible to get together.
I want to keep as low a profile as possible, so ideally avoid colours like Turmeric or Lapiz, so will probably have to be black, Atlantic blue or Indium Grey, and ideally with black mirrors.
I'm going to have to accept a lot of compromises sadly as most seem to be very standard spec.
