Is it possible to convert a 7-seater Honda Odyssey to an 8-seater? If so,...
 

...what is involved? I have a 2001 Honda Odyssey and it's still running fine, but I need extra seating capacity. Am I out of luck, or is there a way to use the seating constructs in the new Odyssey EX models to upgrade my vehicle? If so, how much should I expect to pay for the conversion?
