There is no reason not to take this that I can see. I would make sure the factory warranty starts at delivery and not in 2019. But that being said, I am the very happy owner of a 2019 HSE with all the goodies. It's a custom order I took delivery of in July 2019. I've had no issues. I've been back to the dealer twice: once for annual maintenance and once for a recall software update.
Thanks! Very good to hear. I am adding on some factory warranty coverage to get me 4.5 years/100k miles from delivery. I think I'm picking it up today, unless the deal goes sideways~ HSE, Santorini Black w/ Ebony interior, 19" wheels, and about 10k in packages~
