Why did chevy discontinue the astro van!?!?

this had to be one of the most succesful cargos ever. i bought one for my new biz, it's perfect! it's also 6 years old. but now what will i do for a fleet? i see so many businesses using them, how could chevrolet just abandon those who really count on these vans? what will we use as a replacement? i've seen those freaky skinny, tall things running around, but they are to tall to fit into parking garages where i need to go into sometimes. and the aerostar doesn't work for me either. the full size vans don't do it when parking in crowded downtown areas where you have to contend with the valet parking after 5 pm. they'll let me park the astro, but they'd have me towed if i tried the same with a full size van.
