I never get pissed off when working on the Benz.........but my American made gassers are a different story.

That's part of working on your own vehicle. Just imagine all the funds you save by doing the operating yourself.

I guess my greated satisfaction comes from actually FIXING something! I'm a nasty freak when it comes to fixing something right. I did the timing belt on my Mazda THREE times this summer because I neglected my own mantra and bought cheap parts. I've learned to only buy MB or highly respected aftermarket parts for my 300D's, yes D's. That alone makes them fun to work on, always have a few. And yes, getting old and blind is a real PIA. Rented a borescope just to look at the timing marks on the Mazda. Pretty sad :-(

Gosh, golly, better you than me, low tolerances for stupid.
