In my own opinion, I think the boxster is one of the best cars to get to the engine to work on it...
There are three major ways to get to your boxster/boxster s engine...
1.) From inside the car (behind the seats)
2.) From above the engine (under covertible top)
3.) From under car (where engine is removed from)
Here's a picture from inside my 2001 boxster, with the inside cover removed, the above cover removed, and the engine removed... It should explain more! :-)
Have Fun and Drive Safe,
