I too would highly doubt that such a slight, and honestly, rather meaningless spelling error will have any bearing on the actual validity of the summons itself. It's true though that judges do vary from courtroom to courtroom, generally there needs to be some actual technical error which will remove the officer's ability to show the validity of his actions. A clerical error, such as a misspelling, is usually any basis for dismissal. Even if an officer misspells your name, that is usually not an issue for a court. An officer needs only to show that he/she had probable cause to initiate the stop and then only to show that the equipment used was in proper working order. As long as the officer got your license, and other significant information correct, the ticket will most likely stand. The error you suggest is something that any reasonable person (ok...well, maybe not here...) could have made. Basically, cops are not required, nor expected to know every little detail about every car on the road. "SVT" is basically a trim level to the layman...it really doesn't "mean" anything outside of what owners and enthusiasts know about them.
