Cali emissions pacages are now "Northeast emissions package" beginning with 1999MY IIRC. Not sure if MD is part of that group, but I think my 98 SVT was the last year I could have bought a non-CA emissions SVT here in Pennsy. Ford doesn't charge differently for the different packages, which I found out when Mom was looking for her 01 Focus (which has CA/NE emissions).
EDIT: Just checked, MD does require the emissions package, but the invoice cost is $99 according to
www.edmunds.com on a 2002 Jetta.
