Freightliner FL70 vs Business Class model

[Batman]

Can anybody explain to me what the difference between an FL70 and a Business Class M2 106 is?
I am not looking to get into expediting with either one of these trucks, if anything I'd would do local courier work in the Indy Metro area.
Thanks for any advice anybody can offer.

The M2 is the successor to the FL 70/80 series. The FL 70's have not been manufactured for about 4-5 years. Most M2's have Mercedes Benz engines with some Cats also available. I have driven several up to date M2's and think it is a good truck. The tried and true FL 70 had a bad reputation but if you drove it right,maintained it right it would give many years of good service. I retired a 1996 FL 70 in 2006 with about 925,000 on it and overall had very little trouble with the truck.
Yesterday I drove a M2 flatbed 10 wheeler with a 335 HP Cat C11 engine and it was a smooth riding powerfull vehicle.
