First off, I love the Super Cool video...
Seadoo will be fun.
Jeep will be fun.
Do you live near a large body of water?
Do you live in a region that supports off roading?
Do you live in a mild climate, in which you can jetski year round?
I would consider the fact that the jetski is only good for the summer, and the jeep can keep you occupied year round.
EDIT: PS, I agree, cats are only good with pork fried rice.
