You might have to be a premium member to get the garage option, not sure, but if you click your name on the upper right where it says Welcom, baconator and you last visited etc....

Then look at the top of the page right above your name it will say "user cp" and just to the right of that is the garage link (for me anyways...)

hey i cant find the manage garage link its not showing on my browser. any ideas? i tried the help option under the garage heading
I've been procrastinating but its time to put my girls online
