This is my fifth STS. Great performance and style other than the added spoiler. Poor fit on the rear doors & trim. Bluetooth phone still not functional, traction contol is disengaged under sport shift - no solution yet. Various other glitches (remote start did not supply fuel, transmission stumble at low speeds). Trunk is quite bit smaller than the outgoing model. A potentially great car introduced before it was debugged.
Keyless entry, push button start, Northstar power, interior design, huge DVD screen, overall style is modern yet elegant, awd traction, more of a driver's car than the old model.
Debug and improve the quality of the subsystems, need GM database solutions of reported problems, improve fit on doors / trim, integrate the rear spioler if they must have one, redesign the rear of the car - frumpy.
