All my life I have been around japanese, german and one or two english vehicles, In all of them I did find a few odd ball pieces that were headscratchers like the hinges on any japanese car or the like nothing very odd, except for using a steel mesh as a trans filter and retailing it for 50 dollars

I recently saw an old GM product it was some pontiac sedan with a 3.8 V6 engine, It was at a shop where a new freind of mine has started to work, it was opened up because the factory coolant had actually ate through some "plastic" gaskets

... What????? how does that get approved to fill...

It also made some nice pin holes in the welch plugs too.
Am I looking at things through wrong glasses? because my nissan dealer also gets pissed off if I try to argue logic.
