Ok new vs used ? just lost my a_ _ on a used century class class 8 last year to the tune of 20,000.00 in repairs before i could unload it. I see a lot of freightliners are being used but have a bad taste still for that brand.
In all of the years that I have been expediting, (Since 89) I can honestly say that a Paccar product (Kw, Peterbuilt) has been the most dependable and durable trucks I have owned. Sure, they are more expensive than the rest, both new and used, but they are far more superior in many ways than the rest.
If it was me, And I was to go that route again, I'd get one of TMC's used black peterbuilt's, with the 119 inch hood, because they spec'd them out to be lightweight, but yet decent power, and they have an awesome maintenance program. The expeditor services trucks I have mixed feelings about, even though they are spec'd out nicely.
