What does everyone think? With prices of diesel and improvements in gas engine technology and longevity, are we trying to hard to "be different?"

420s are a bargain, at least around here. Economy is about a wash (dollar to mile figure), yesterday No 2 was 40¢ more than 93... and they can burn 89 if you desire.
I've seen people report 18-22mpg freeway with them. Not bad, performance is adequate too. Low 7 sec area 0-60mph according to my booklet from MB. Euro 380 true duals will fit to help it breathe better.
FINALLY there are ALUMINUM upper guides for the M116 too! They're about 3x as much as the plastic (which are what, $5/ea?). They are just like a tensioner rail with the rubber on the rail. You will basically be set for the next 150k until you do the chain again. The M116 (and the 117 in the 560) pretty much don't wear. They do have some valve seal issues after a while but the bottom end will keep on ticking.
