I'm looking into buying a MT 05 RX-8. I know very little about the rotary but I know more than the average person would know if you asked them. I emailed this guy about his RX-8 and he told me that it has been in storage for a while and when he started it it misfired for 30 seconds then started up and ran perfectly. Is this just due to sitting for a long time or could it be something worse? I'm debating between getting this one ($4500) or getting another 05 with only 44k on it ($6800 but will try and get him down). Any help or advice would be greatly appreciated!
