Hi,
I'm purchasing a 98 Ford econoline 5.4L club wagon xlt on 12/13/2012. I'm by no means a van (or even a Ford guy) but since it needs to be handicap accessible for me and I want to tow with it, I'll settle. I have an 09 dodge caravan as my primary vehicle and the Ford will be my secondary vehicle for performance upgrades. I eventually want to build it up to a fast sleeper/toy hauler but with loud exhaust. What is a good website for getting (possibly cheep) performance parts for this van? Also, what kind of common problems should I be aware of?

Thanks guys
