Appearence: Jazz's vehicle mode is a white Porsche Martini race car with red and blue stripes. He looks rather plain in car mode. He has a nasty tendency to yellow, and unfortunately his front wheels tend to spread outward under the car's weight. This hindrance is caused, of course, by the features of his transformation, his arms are under the hood and they drag on the surface of what he is on. His windshield breaks easily because of it's thin plastic make, as does the roof of the cab.
In other words, drop him and he's history. His robot mode is somewhat more impressive, with a well designed proportionally sound figure and some very cool and colorful stickers.

Transformation: His transformation is quite complex and it takes a while to memorize. Feet are formed from the back bumper, legs when the feet are pulled down. Arms are swung out from under his hood, where his tires cover the shoulder sockets. His midsection is folded out from inside the cab, on top of which is his chest, formed by his front bumper, and his head, from under the hood. Makes for a pretty cool looking robot.

Posability: This is the most dissapointing aspect of the Jazz toy's design. His legs and toes have no movement. His head can look down, but this is useless because he's looking down behind his chest. His shoulders have limited rotation, which is a big problem because he can't "aim" his gun properly. His shoulder-mounted missile launcher can be raised and lowered but it must be done carefully so as not to pull it off.

Accessories/Features: Jazz comes with some very impressive-looking weapons, including a chrome laser rifle, a black/chrome missile launcher with three chrome missiles. The missile launcher has almost no propulsion (if any) but that is easily fixed with the spring of a pen inserted into the barrel. Mine can now shoot all the way across my bedroom. You will find that this can be done with many of those old TF projectile launchers with no propulsion.

Overall, Jazz has numerous good and bad points. I give it a 5.
