Higher octane fuel does OT burn hotter, does not contain any more energy, and will not make your teeth whiter and cure baldness. Octane is a fuel compound, Octane Rating is just a way to measure how resistant a fuel is to premature detonation (and we all know how embarrasing that can be). In a gasoline engine, you want fuel to burn when the spark hits it, not explode when compressed.
If your engine isn't knocking, going to a higher grade of fuel will make absolutely no difference except you'll spend more money to buy it. Most cars have some way to accomodate for poor quality fuel - in a Saab turbo, boost is reduced, and in later model Saabs, more fuel is used and timing is adjusted. But if the engine isn't knocking, the engine control system can't 'turn up the wick' and get more power.
Hatch latch- Bend down and look up at the hatch latch lever from outside the car. The lever is just a flat piece of metal with two thin arms that disappear into the section that holds the license plate lights. Move the lever - are both the little metal arms still in place? The lever is big and flat, but it skinnys down. One arm is the hinge for the lever, and the other actuates the latch mechanism. Over time, I've seen the arm that actuates the latch break from metal fatigue. The lever still moves, because the hinge arm is still fine.
If this is what has happened, you need to replace the latch mechanism. It comes as one piece. You can buy it from the dealer for about $75, or maybe get it from a junkyard. As a note, the same mechanism is used in the older 900 and 9000.
Good luck!
