You made a point in that there are GOOD modifications, and bad modifications. Mostly that is in the eye of the beholder. Hell, some say the Borbet wheels I had on the 400E were wretched... To quote one purist I was talking with the other day..."it is only okay if it has a MB part number for the item". Speaking of compromise, how about the compromise of time to fix vs fixing it right. There are many questionable "techs" out there who do poor jobs then give people like Benzmac a bad name. If your surgeon could go in through a scope and fix a tendon in your knee would you rather he ripped the joint open like a biology dissection project just for the sake of "hot rod medicine"?
Just my pair of cents...Lee
