My new favorite car search engine is
https://www.autotempest.com/ since it searches multiple listings at once and can sort results based on different criteria such as distance or price.
I'm always telling people the Ford Fusion Hybrid is super nice and gets 45 MPG. I see a plug-in version called the Fusion Energi for just over $10k on Autotempest. If you can stretch the budget, I highly recommend it.
