Regardless the cost savings was also 113 versus 119 - both V8s. 104 motors and 119 motors are not particularly sensitive to oil change intervals. The 112 motors were in court in less than 4 years from their introduction, a truly stunning feat of shoddiness, and Mercedes folded like a cheap suit. The only cars out of warranty were those with more than 50k miles. I think 112/113 owners are in denial.
