6.23 after all displacements is as big as I possibly could get in this car into the trunk, and it still pushes the back seats forward a tad, 1/2 inch of clearance to fit it in the rear doors...I can give you all the measurements if you like, should work in all S-Series Sedans '96-'02...what year and model is your car?
Just looked at your Gallery, '94 coupe, I think you should still get a decent box in there...hit me up on MSN Messenger I can show you what to do to get the biggest box possible in your car...I did a bit of work to get mine in but it's in there and works.
