Guys, please don't dump on Gilly.
This is a discussion about 2 Mercs that are at least 25 years apart in terms of technological development and electronic innovation. As mentioned before, there's no comparison.
BUT I do know that it's a much easier to wrench on a 126 than a 140. Then again, it's easier to work on a slant 6 Mopar than a Dodge Viper V-10.
