#1 - you will need to be carefull to find one that will fit into the opening of your car. Doesn't matter if it sounds great in the box if you can't get it through the opening and mustangs have small openings.
#2 - be aware that those recomendations that they gave you are the required volumes that are needed AFTER you subtract the volume that the subs motor and magnet displace. There is another number on the spec sheet that will tell you the motor/magnet displacement. This number while small will need to be subtracted from the boxes displacement to get the true volume of the box.
#3 - I have been installing for almost 15 yrs and the majority of the boxes I have built were sealed in keeping with my KISS philosophy. I have never had a complaint with a properly built sealed box that could not be tweeked or tuned either through some kind of frequency manupulation(EQ) to make a completely happy customer. I have seen alot of ported(especially pre-built) boxes that make port noise or make a good woofer sound bad that led to something beind jammed into the box since it sounded better that way....
#4 - the General rule is that a smaller box is tuned for a little higher freq(kick drums, toms, ect) and will keep the sub in control better because of the airpressure created by the moving speaker in the box. It will also not need as much power and will run less chance of blowing if it is not overplayed but also will not play deep bass as well as a larger box
What ever you do make sure you mount your box to keep it in place.

A couple little clarifications...
Woofers in sealed enclosures need more power to make the same volume as a ported enclosure. The woofer has to work hard the smaller the sealed box to overcome the vacuum created in the enclosure by the cone moving outwards.
Generally speaking, a ported box will always be louder then a sealed box with the same dimensions.
The biggest problem with ported boxes is their size. The size of these enclosures generally limits port placements and sizing, therefore port noise is created. The larger the port diamter the lower the velocity, keeping everything else equal, and therefore the less port noise.
