Basically the same as what mattski said, except:
I don't ever take off the big black shield to change the oil; if you crawl under the car and look up towards the radiator (front) you can see the oil filter. If you use FRAM filters they have the rubber on the end so I just tighten them by hand. Much easier than removing shield, using filter tools and then reinstalling shield. Just be aware that you'll get a little oil coming down into the shield

Also, I thought I'd add that even with the shield in the way, the SVX is the easiest car to change oil on, that I've ever tried anyway
