Trust me, black cars are best way to spend an afternoon with cleaning...every week at least. In UK, you'll have a real fun with waterspots.
Silver or Mineral gray are good options. I had a crush on cool vanilla but not sure it will last through years. So see the pic.
About engine... for me US cars are all about the pounding sound of large V8. I'll let the CRD for MB German cabs. But I understand the subject "fuel budget" in Europe.
I own 2 V8 cars and recognize it's expensive out here. In Switzerland the 95RON is at €1.06. With a 16 l/100km, it's about €212 a month for a 15'000km driver. Definitely not for everyone.
