Well folks,
Your right and I'm wrong...
Just looked at my 98 & 99 Catalogs and both have the Z as the standard engine. Guess it's been a long time since I looked at those...and every time I see an SE it seems to have the 2.5 thing on it...so it must be a popular option...
Anyway...I learned two things today...
Thanks also to Tony for ... uh ... adjusting my vision!
