It's always nice to be able to show a consistent service record right through - but to be honest I don't think it's necessary with so little use. I skipped one of my services mid-lockdown - just had the annual MOT and did a check over/tighten all round myself - noted in the service record with date & mileage. (Different story if under warranty, of course).
That's assuming, of course, that the dealer pre-sale service was, indeed, "comprehensive" (unlikely, I should have thought). Worth finding out exactly what they did perhaps. What about brake fluid changes? Your MOT should cover most of the safety items.
Others will be along with - no doubt - differing opinions!
