I'mn ot a mechanic.. a hobbyist at best, but I do like doing my own
minor repairs. I usually buy the Haynes or Chilton manuals but they
don't exist for my '93 90S. Is this DVD set worth buying?

I want to do some pretty simple things like opening up he instrument
panel to change bulbs, and also some more difficult thinks like changing
my fuel pump (and fuel filter along with it) as I'm pretty sure is on
the way out.
I don't think i'm daring enough to cahnge my own brakes and rotors yet..
