Car model profiles should include passenger capacity

It would be really GREAT if the profile for each car model available included a passenger capacity number. This would be particularly helpful in the small car category and the SUV category. Some small cars only have seat belts for 4 rather than 5. And some SUVs can seat 8 while others don't seat any more than a passenger car. This seems like vital information when you're renting a zip car to transport a group of people.
