factory service manual
.. issued by GM to the dealer mechanics and always
available in the open market (ebay, etc.) but not at the retail stores.. INVALUABLE !
Gary is 100% correct. We, the Allanté guys, dont move without these manuals.
typically, they can be had in the range of $20 to $75, depending of the seller and condition.
i also like the idea of having a OBD/OBDII reader
in the tool box. some cars cant lieve w/o it.
lastly, the OWNER's MANUAL
regardless of car model, IMO this manual is not an option, but a must.
on your '96, this one is also avail on CD for around $5
