Brian, My two cents...... I have a small service company, we currently have 3 Toyota Tacomas for service trucks. I have been running Toyota's since 1990 ALL with the bullet proof 4 cylinder 2.7L engine.
Toyota no longer makes a 2 door truck, your choice is access cab or 4 door. All manufactures have come a long way, again this is just my opinion , a few years ago we sold a 2003 tacoma, 2 door with a little over 410,000 miles,(we needed extended cab for extra storage, was the reason for selling etc) a landscape company purchased it and is still going strong! Last Fall I saw the truck, it had about 440,000 miles, other then brakes, batteries here and there and exhaust.....no issues.
Philip
Good luck on your purchase
