You're going to be spending an average of 10 hours a week in the car, so that’s 500+ hours per year: Trust me, you really want to make sure they’re comfy before you buy!
DT in Wrexham might be a bit closer, find a hotel and enjoy the Welsh roads over a weekend? I definitely wouldn’t buy before trying, too much of a risk if it’s not comfy or just as bad, not grippy.
