unless you particularly want leather the classic trim is ok, upgrade to the comfnav+ pack gets you heated seats, auto aircon,centre armrest,park distance control,storage pack which gives you an adjustable boot floor plus a buch of techy enhancements to sat nav etc. for an increase of £900 to the ap.
i have the countryman 2.0 cooper s auto with the comfnav+pack and i would say the upgrade was worth it, i also went for the exclusive as i like the leather trim and seats.but classic is good. it all depends on what you need. even on top trim auto boot opening waggly foot is still another extra at £375.
fortunately my main requirement was a higher driving position so anything else was gravy, and the fact that stratstone gave £500 off the ap meant the comfnav+ was basically free.
