Letterman's Healeys

Healeyophiles,

This month's FORZA, a Ferrari magazine, has a feature on David Letterman's 
Ferraris.
But according to the article, he also owns three Healeys. One was identified 
as a Sprite, the other two weren't described.  Anybody know what he has?  
Boy, sure would make a great story for some British car magazine to feature 
(nudge, nudge, wink, wink, Gary,)  Maybe even a Top Ten Reasons for Driving a 
Healey?

Don't own a Ferrari, but I can dream can't I?
