heat index won't affect the car. just like wind chill won't affect it.

Any ideas what I should be looking for? Could it be as simple as a thermostat, or a coolant flush? I'm driving 400 miles to the Porsches to Oxford car show next week so I need to get this sorted.

was the roof open or closed? anecdotal evidence has shown (for me at least) that when the roof is open (retracted) the car runs hotter when stuck in traffic. additionally, running the A/C seems to help a little.
the warning light has two "displays." a steady light indicates the temperature is too high, a flashing light indicates the coolant level is too low.
i would think if the thermostat was not working, it would heat up rapidly and consistently, not just when stuck in traffic. that said, it would be one of the first things i investigated after making sure the coolant level was correct and after cleaning the radiators.
