I just added a way to add EPA estimates back to your car profile if you disabled it:
Click on Edit This Car on your vehicle profile page, and then look for the line that says: EPA Estimates Disabled, click enable, choose your model for estimates, and the estimates should appear on your car profile.
We have EPA estimates for 1998 Saturn SLs, but nothing for SL2s. (Here's the 1998 Saturn list at the EPA website.) I'm not sure what the difference is in on those models. If they're basically one in the same we can shuffle things around here and use the SL numbers for SL2s.
Fuelly doesn't show any EPA estimate options if there's no matching model in our system.
