There were two different plastic ramps at Autozone and I picked up the cheaper ones -- was about $45 if I remember correctly. I chose the cheaper plastic ones because in addition to the 10,000 pound rating the FF is one of the lighter cars around so I don't feel too concerned.
For me, the hardest thing about seeing the oil level after changing the oil is that the new oil is so clean it's really hard for me to get an accurate reading of where the oil level is. I mean, pulling the dip stick out and putting it back in leaves a coating along the tube and when you pull it out that oil get all over the stick so it's hard to see what the level is with all the other oil on the stick.
What they should have on the stick is a couple of metal bands, one above and one below the oil range so that portion of the stick can't contact the tube and screw up the reading.
