Titanium is very hard to cast at high quality standards and must have very tight tolerance's on temp control during the process. I use to deal with Titanium foundries in China and only certain foundries could handle the tolerance's. So that is why it is pricey! Certain Aluminum alloys aren't so cheap either. I have a titanium bike which is indestructible, i bet a titanium cobra would be sweet!
