I was offered a similar deal last month by my local dealer to entice me out of my 2019 IS300h F Sport with Takumi pack with only 12k on the clock.
I was sceptical at first but the deal kept getting better and better. When I checked the value of my IS against the payments I make each month it was devaluating faster than I could pay it off.
The move to a new ES300h F Sport with Takumi pack for no extra deposit, lower payments than I was currently paying, and dash cams, Supagard, boot liner, reduced service plan etc, etc. Too good to say no.
I was planning to purchase the IS next year, but having had the ES for 48 hours, it was an easy decision to let it go.
Having had the ES for a few days, it is a completely different drive to IS and I'm very happy with it.
