Welcome on board, Mr Bowly101. First, take all your guilt about PIP award, Blue Badge etc., bundle it up in a bag and chuck it in nearest supermarket recycling centre (when they open again). I, too, felt like you when awarded benefit/badge. But then realised I would really rather have full use of legs back again rather than take the benefit. So just make the best of it, mate!
Motability really is a fantastic resource. As you see, choice of vehicles is a bit wonky at moment. Hopefully it’ll get better. But the all-inclusive nature of the service is brilliant – you don’t have to phone, email or write to insurers, tax people, RAC, tyre firms and so on. It’s all done for you. This, to me at least, is such a relief. Dread calling all those people who are going to try sell me rubbish.
Finally, WMC forums are a fantastic place to be. All here know the issues you’re facing and are keen to help. You will get answers to anything you care to ask. Then head over to Off Topic for some amusement/entertainment!
