The first picture that shows up for the Mazda DLC for Mechanic Simulator 2018 is a car dying of rust. Ouch.
(and my Mazda is 7 years old, lives outside full time in the rust belt yet doesn’t have any rust.)
I have no idea if this version is any better than previous versions which were rather simplistic and tiresome. I haven’t purchase this version and, unless I hear otherwise, have no plans to do so based on my previous experience with the franchise.
