I've read a bit about this but let me tell you my experience:
The car is a January 2020 1.3 EX CVT Navi. It has 3900 miles on the clock.
15th May 2021 - We Buy Any Car - £13,350.
20th June 2021 - We Buy Any Car - £13,900
24th September 2021 - Cazoo - £16,750
Today (29/09/21) - We Buy Any Car - £16,770 and Holdsworth Honda Warrington £15,390 as a part ex.
Some good offers on new Hondas. Seriously thinking of going for a Mk4 which, the dealer says, they have several in stock.
