Most reliable DD and best gas mileage

[antlip]

Like the title says. Whats the best DD, best gas mileage cheap car. I was looking at 4 door saturns, civics and neons. So far I have seen the saturn up to 40 MPG highway 5 spd. Whats the more reliable out of these cars and cheapest to fix if something goes wrong? I may need to buy one of these little cars for a new job. I might go into bridge building and I would be driving 60 miles there and 60 back each day. But wtf for 33 dollars an hour I will buy a cheap car, get it dirty and drive it a million miles.
