You guys that buy parts all the time are going to say, 'well duh!', but I don't care. This is just too cool.
I'm trying to sell my car at the moment, and my heater hoses look like crapola, so I figured it would be an easy fix to clean up the engine compartment. I was having a bit of trouble envisioning which hose was which, and being a lazy ass, I did not want to walk the 15 steps out to the garage. Then I notice this 'view in parts diagram' link next to the part I'm looking at. Boom, up opens a split window, with the diagram (zoomable) on one side, and the entire parts list for the diagram on the other.
That is freaking COOL man!!!!
Hats off to you Wayne.
