For the year I average 34 overall with mixed driving over 5 years. More highway will net 36. You will see 40 if you keep it under 65 and on flat and level. Mountains will make the challenge of MPG. Since you have the insight, you understand the range of MPG and driving conditions. my 14 hybrid has had ZERO issues with the real mechanicals (engine/drivetrain). A few body parts have been repaired. The tires are your biggest challenge, so there's not a lot to worry about. My 65 year comfort in the tech stuff is good. suspicious, but good, so far.
