i have a 4 month old son now, i bought my 99 honda passport (isuzu rodeo in a costume) with my wife pregnant--and after reading about it on these forums, i have faith in this vehicle--and i didn't even have the luxury of knowing the previous owner.
if it breaks--know that these forums (as well as others) have people who either have had the same thing happen to them, or know how to fix it...or their name is amigo-2k---and you're a god!
everyone on here can help. this is a great place--just use the search as any problems you run into--most liekly are remedied under these pages.
check amigo-2k's FAQ page (found in my sig for quick reference)
other forums--planetisuzoo.com and 4x4wire.com have a wealth of knowledge. good luck and welcome to the dark side...
