Just about anything made in the last 20 years will have readily available parts.

For a daily, it's really difficult to beat a Japanese 4 cylinder something. It almost doesn't matter which flavor you choose. 8k mile oil changes for $15, 30mpg on regular gas(Edit: My Forester not included, that AWD sucks some fuel........). That and tires/brakes will likely be all the maintenance it needs the entire time you own it. If you cross the ~100k mile mark with it, expect to do a timing belt. Couple hundred bucks if you buy the parts and do it yourself, couple grand if you pay a shop to do it.

In the last few years, the American marques have really stepped it up, too.

We're at a really fantastic time for cars, lots of really great options.
