My current 206 is a light one (sub 1800lbs), and with three variety-sized kids and if you and the missus aren't too blobby, you can take easily enough fuel for 2.5 hours, which will get you the thick end of 300 miles.
A new 206 is a nice machine: I'm just going through the motions of bringing in a 1983 machine whose airframe has been compeltely refurbished and most components zero-timed. I'm hoping to enjoy the "joy of new" feeling on a machine that won't make my eyes water too much!
If you hurry up, you can still bring into the UK via Denmark VAT-free (if it's a personal machine).
