I guess that I would ask why do you really need the Sierra and the Xterra, when you could just drive the Sierra and not giving up that much gas milage.We have 2 vehicles, the '21 Sierra HD sits in the garage unless we're towing the trailer or going somewhere over 40 miles which is just about anywhere else not local. The other is the '02 Xterra with 155k and no known issues. The big truck gets 16-17 on the highway unloaded and the Xterra gets 17-19 so with two 50 lb dogs usually along the truck does road trips.
She'd like to give the X to daughter and get something plug-in for local trips. Not new and not a sedan. Local dealerships are big 3, Nissan, Toyota, Honda, Subaru, Mazda. Not interested in a brand I have to drive 100 miles to Phoenix to a dealer if needed. We could get along fine with a PEV as the 2nd car but I'm not sure about giving up the X and having 3 vehicles is out. It's inevitable to happen at some point unless she loses interest. What can we look at for $20k or less?
Maybe sell the truck and travel trailer, get a Hummer and keep the Xterra!
As for what hybrid or EV to get, pretty much every manufacturer makes a great option now. Its just a matter of picking what you like. Toyota is probably your best bet, as they have been in the hybrid game for a long time and know what theyre doing. The RAV4 hybrid is awesome if thats something youd be into.
