986 Hardtop Dimensions, about
: 48" L x 60" W back / 46" W Front x 15" H
I originally wanted to pick mine up with a Grand Cherokee and it was not even close to fitting, they are too wide. Rent a truck or install the spinlocks and pick it up with your Boxster. It will probably be noisy until you take the time to adjust the hardtop and it "settles" to your car. I've written about how to adjust hardtops before.
