Henna Chevrolet

Called to try and get part number for my 99 Astro van. The person from parts will provide price and availability but not the part number. H's reasoning was "... he's a commission employee and customer trys to get the part number and get the part cheaper from some where else ... therefore; he's not giving out the part number...". I don't appreciate that they are the "offical" source of part number and hold on to the information to make customer pay the exterme inflated part price. I happened to bought my Astro there when it was new. I'm trying to save money and repair it myself in this economy. Needless to say, I'm extremely disappointed with the service ... even we all contribute and "own" part of GM now.
