Ajn,
you can buy privately or lease, or organise zip cars, or just use Uber. When I was looking at the CLA, they couldn’t even give a wait time! Don’t think I would wait six months for a car, on motobility, if it’s car I wanted on the scheme, I would make it my job to either ring around or visit as many dealers as possible to see what allocations they have, or stock cars, money in a brown envelope might help, and a bottle of Prosecco may sweeten a deal.
