Car length in the designer

Hi,
Would it be possible to at least have the car dimensions under the test section in the car designer? This would be useful as a guideline when creating a car. I don't want to make a cheap sedan and eventually realise it is 195 inches long... Is that something that could be done fairly easily? Since the dimensions of each part are probably calculated using XYZ coordinates, it should normally be as simple as putting all these coordinates together.
Otherwise, the car designer is great stuff and a lot of fun!
