Apart from the snob value of having the latest reg plate why wait? It won’t make any difference to the residual value of the vehicle at the end of the lease 🤷♂️
A car will ALWAYS be worth more at resale if it was registered in the first month of a plate change rather than the last month of the preceding reg number.
Not to a dealer at the end of its lease, maybe cost a punter more who thinks he’s getting a younger car but Motability aren’t getting an extra £1k for it
