Three good reasons why I still do my own repairs.

Found on a '92 F250 I recently purchased....

Reason #1: Exhaust shops are too lazy to tighten down the clamps on the silicone AIR tubes running down to the catalytic converter (just fixed myself):

Reason #2: Zip ties on the brake line-hose junction :

Reason #3: Cable clamps holding the front and rear parking brake cables together:

Looks like I still have some work to do.
