because I have worked with some great vendors from TT.net. However, on some parts the markup doesn't seem right. The adjustable T-Rods from this eBAY seller aren't much less than the adjustables from our vendors - but the adjustable arms are $140 less and they do look nearly identical. I bought a lower radiator hose (aluminum) from this guy several months back and it saved me $50 or so on vendor price. He has good feedback and answers questions. Saying things like "DO YOU LIKE YOUR Z?" are pressure statements and have no validity towars the quality or comparison of one product to another. eBAY DOESN'T just mean SAVINGS - many vendors provide excellent warranty service on eBAY. I sell stuff myself and I guarantee you that my service is as good as any vendor of the same merchandise (local or online). Vendors need to be a bit more fair about the issue and make fair comparisons based on good info.
