Nix,
I think a steering wheel lock is a bit passé these days. Thieves simply cut through the wheel to remove them and on a Pagoda steering wheel, that would be extremely easy. Instead, I would recommend that you have a "kill switch" installed. This would kill any potential thieves.
Okay, I kid. What it would do is to cut out the starter until you flip this hidden switch. Very simple, very discreet, and very inexpensive to wire up by your mechanic. (And since you have an automatic, thieves couldn't roll-start the car either.)
