I have 4 kids and the 7 seater has died find that as they are older and get around more themselves the 7 seater is rarely driven full in fact as I work full time and dont do school runs it is usually driven empty. Was thinking of going for small car and then when needed all 6 of us to travel hiring a car on those rare ocassions anyone see any probs? could I negotiate frequent use rate with car hire co?
