Freightliner And Peterbuilt Company Trucks

Hey guys and girls I was just wondering if any of you know of any companies that still use freightliner classics or Peterbuilt 379's as their equipment. The Kenworth w900 is nice also. I've always been fond of those models growing up and was always interested in driving one. I'm looking to start my career soon once I finished with my medical with prime inc.. I've noticed that most companies don't use equipment more than 3 years old and most use the freightliner Cascadia and Peterbuilt 579 models, which I'm guessing they use because they are more aerodynamic which would help save on fuel costs. I know that they stopped making classics in 07 or 08 I think but freightliner has the Coronado model that looks just like it. The only company I've found so far that uses the latest equipment that looks similar is TMC. Its not a deciding factor as to who I will drive for but one day down the road after I get my career started it would be an option to drive for a company for a Lil while that uses that type of equipment. The only guys I really see driving the Classics or Peterbuilts now are owner operators and I'm not really trying to go that route just to drive a truck, but they do look awesome especially when they have the chrome visor and all the running lights along the sides and bottom.
