As said it’ll be a 23 plate now or next month.
I’d not fix my sights on buying from Motability, they’re well known for overpricing their cars for customers, afterall they’d much rather you continued on scheme. However, if you’re dead set on keeping the car, keep an eye on Autotrader after it’s returned. It’ll get picked up and taken to auction, then will hit a dealer’s forecourt after any servicing and ‘stuff’ needs doing. I’d give it a week and keep checking daily, it’s highly likely to show up for much less than MB would have wanted.
I'm Autistic, if I say something you find offensive, please let me know, I can guarantee it was unintentional.
I'll try to give my honest opinion but am always open to learning.
