I need a favour.

At the moment I drive a Vauxhall Zafira, it is a car on the mobility scheme and in September the car goes back to the dealer as I have had it on a three loan through the Mobility scheme. However in a few months the family are planning to go on Holiday for a week and in the car I need space for my wheelchair, charger, ramps and the family dog. In previous breaks away, in this car, we have managed to load the car with the chair, charger, ramps and the dog, but the luggage has been a bit of a squeeze. I have a roof box, from a previous car, but no bars to attach it to the roof bars which the car comes with. The bars for this Zafira cost about £100 and in the long run would be a waste of money, seeing as the next car we are looking at, not only comes with roof bars, but the bars that go across. I need a favour from anyone on my list of friends, old or new, ( In Oxford area.) to ask if any one has the bars for the Zafira that we could borrow for a week. I would really appreciate it and look forward to any response. Thanks. Clive.
