Finally saw a new Alternator at the store today. It was Silverstreak, one of 'em on the shelf amidst dozens and dozens of Sideswipes and Smokescreens (hmm, all of them are "SS" names, what does it mean?). I wandered around holding him for a while, but in the end didn't bite. I will say if he had come out the same time as Smokescreen I probably would've picked up
BlueSilverstreak instead. The silver paint job looks much more like a real car (not glaringly plastic) and I think I prefer the "street edition."
(Who am I kidding, someday I'll own it, but not today...)
