Or could be just a loose battery terminal. Try twisting the terminal if it turns then it's loose, that will also cause intermitent starting. Plus check to see if it isn't full of acid corrosion that can cause a bad connection too.
135 in my 2000 Celica GTS. The car was loaded with camping gear and my wife so I had to downshift to 5th gear to pull me up there. But it was smooth a very stable. Could have kept going but didn't want to push my luck with the cops.
