Brian said he had no problem with the windows up so I doubt it would be the ventilation system. Developing a headache and nausea would seem to indicate exposure to high levels of carbon monoxide (which has no smell or taste) but I can't imagine how it would get into the passenger compartment through the open windows. Just a thought, it is possible that when the window is open it creates a low pressure area inside the passenger compartment preventing any CO build up from escaping.
have you experienced this with the top off? You can buy a CO detector at most hardware and home improvement stores to verify the presence of CO. Home Depot has one for $15. (just a cheap one that has an alarm if levels are unsafe, one with a parts-per-million readout would be more expensive) 50 ppm is considered the "safe" exposure limit. CO levels of 200ppm can cause a headache after 2 hours exposure. A severe headache and nausea after 2 hours would indicate levels higher than 500ppm. I would have the exhaust system fully inspected for leaks. You could also have the exhaust tested with a 4 gas analyzer to make sure CO emmisions are acceptable out of the tailpipes. In any case, for your own health and safety, I wouldn't drive the car very far if you are getting headaches and nausea.
