I also have a voltage blue LS that I have owned for over 15 years. I would make sure the timing belt has been changed, and if you are not sure, I'd make sure to change it. If nobody messed with the engine/transmission, it will last an eternity (as long as it is not allowed to rust). I have had zero problems that were not routine maintenance, other than a noisy AC pully bearing, which cost 15 dollars to replace. (And needing a new rear caliper- my fault for trying to use a c-clamp when changing the brake pads- didnt know they screw in rather than push in). But, the timing belt is essential. Good luck with the new car!
