Winter range is around 125 miles, summer can get to 160 – 180.
The cold makes a big difference, the way it’s driven and having the heating on.
On the motorway as long as you don’t thrash it and stay a steady speed say 60-65 then you’ll get the range. On A roads put the regen braking on and you’ll recover some miles.
You should be able to do the 120 mile round trip.
Mine doesn’t have a heat pump fitted so if the one you’re looking at has one then the range will be better.
Worse case scenario is you plug it into a charger for 20 minutes to top it up.
If you’re near Chorley, lancs then you’re welcome to have a look.
