If he is talking about the Xj wagoneer, it should also have a HP 30 w/o the vacum disconnect. The only problems I know of with them besides the insane amount of vacum and emision tubing is the injectors like to leak, the pcv system barley worked, and the power window motors tend to go bad at the most inconvient time.
How much is 5200 cdn.... that sounds kinda high to me.
