I’ve never leased privately but I’ve been keeping an eye on it recently. It seems as though good lease deals come and go as quickly as they do on motability. Depends on your search criteria obviously.
Its good that you’ve got 3 cars on your shortlist as I doubt all 3 would leave the scheme all at once so you should still be able to get something that suits your needs.
If you’re in a position to extend your lease you could do that and then you’d really be able to take your time and keep an eye out for a really good deal.
