The Vauxhall Crossland deal has already been posted on here, 2 months ago, and is now showing as expired. However, Crossland's are still available at the same price, starting at £12995. Similarly, they are offering a very good discount (or even better) on 2020 pre reg Astras, the one shown here is just an example.
All just have delivery milage.
Unfortunately the deal seems only to be on manual cars. The Crosslands are all petrol whereas the Astras are mostly diesel.
Excellent discount on new... I think we're looking at about 38% off new list price.
