what to do?
 

I need an advice in freightliner a cascade with a Mercedes 400 engine 2008 has 750k or an internatiol prostar 2008 cuminn 450 610k is about same prices 35000

I would stay away from the brand specific engines, like Mercedes. Parts may not be readily available when you need them and the cost of any proprietary parts are always more expensive. I would stick with Cummins, Detroit or CAT.

I heard the Mercedes is made by Detroit ? That's is someone tell me Thank you for you advice
