That's pretty typical for cars like the F-Type - people use them as weekend cars and they don't cover many miles. If a car has genuinely covered almost no miles between MoTs it might be a concern - consumable items like the tyres might be perished - but a few thousand miles a year should be fine. We'd recommend looking for one with evidence of regular servicing, too - even if a car hasn't been used, it needs to be serviced regularly.
