Go for the highest spec you can if you need the range. I have a 2019 Nissan Leaf 40kw Tekna which is brilliant for me as I'm a volunteer driver and usually just potter around locally so 160 miles is fine and I only need to charge it (at home) once a week. I just visited my sister in the New Forest at the weekend and charged at Winchester Services through Ecoserve and it was free.
Haven't heard of ecoserve before, are they new
