It sounds like you're comparing used ICE vs new hybrid? What's the difference of used ICE vs used hybrid? The tax rebate should also depress the used prices for hybrids since if the differential is too small, people will buy a new one instead. (Although I guess used hybrids are hard to find everywhere?)Sorry for the late reply. I work in healthcare, so you can imagine how slow it's been lately.
To clarify, I was referring to used ICE Pacificas, which is why I mentioned "gassers". If you don't mind buying a previous rental, I've seen 2018 Limiteds are Hertz for 23k and less and 2019 Touring Ls for <20 k. Dealers typically have similar vehicles or 1.5-2 k more. That's why I was saying it's hard to justify spending close to 40k AFTER rebates (taxes and registration are a bear here in Cali) when I can get a 1-2 yo model with 40 k miles for half that. I love the idea of a plug in hybrid but I love the idea of saving 20 k more. I could never make up the difference in saved fuel.
