my 2 cents.
The VW TDI's love the open highway, they have long legs and can cruz the higher speeds. If can find a a nice one with a 6 speed. Look for a Jetta , golf, Passat or Audi A3. I have had 2 of them. I will tell you you need to keep up the maintance and avoid the dealers. These cars really require the owner to know a little about the cars, it's not a toyota.
Speaking of which, if you want reliability, get a Toyota. I'm guessing your avoiding hybrids because of reiability, the toyota hybrids are very reliable.
Lot of new cars to pick from, my dad had 2020 hyundai Sonata with the NA 2.5 litre engine. I didn't drive it much, but was impressed with Gas miliage. It's rated at 38 mpg. strong power.
