The best fuel mileage was the Jetta diesel. My brother-in-law had one and I drove from L.A. to Fresno and got 50mpg.
Get a Mazada 3. Great gas mileage and it is peppy.
I am seeing some stations at under $4.00 a gallon now.
Any of the Toyota hybrids would be a good choice.
My friend has a Rivian SUV. It is really nice and stupid fast. No way I would do any road trip with an electric vehicle.
3.75 is not too bad.
Be a man and get a Prius. The newer body style looks nice and you don't have to worry about being considered the worst driver on the road as Tesla owners now hold that title.
