GM drivetrains especially transmissions are untouchable, for comfort ill take 94-96 fleetwood brouham over any of those cars, plus 25mpg outta of a 4300+ pound car is unheard of, add in the aftermarket for the engine, cheap replacement parts, and advancement of tune, and solving of problems since they where new(because the lt1 is a performance platform), I dont think it could be beat, plus you can find a clean one under 4k.
