Where did you come up with 60 cu/ft?
I'm going to bet that a Miata has 59 cu ft of interior volume..

Manufacturers typically publish this information with their list of new car specs. you can find interior volumes on just about any car review site- edmunds, motor trend, car mfr brochure or website, etc. As there is a standard test method to calculate this number, I would rely on any of those sites to provide usable data (Mfr's owner or service manual data first).

As a side note, the standard measurements for interior volumes to classify cars include trunk volume. Reference: http://books.google.com/books?id=F3Q...page&q&f=false
