2019 Peterbilt 579 vs 2018 Freightliner Cascadia 126

2019 Peterbilt 579 with a Paccar MX13 , 550k miles - it drives, but you have no idea if it has any major issues, where it came from and how well it was taken care of

2018 Freightliner Cascadia with a Detroit dd13 or 15 , 650k miles, you know the company that owned it before and the actual driver. No major issues, and you know it was well taken care of.

Both going for the same price... which one would you choose and why?

 

forgot to add the engine of the freightliner. it's a detroit dd13 or 15

 

the freightliner has a detroit engine, either dd13 or 15

 

so detroit even though it has about 100k miles more on it? are paccars that bad?
