I've read some info on the Saab boards about problems with the connectors under the pwr seats. Sometimes I guess they come apart. The car has been away at school with my daughter for a couple years so I haven't been able to check it. Might be something that simple.
The other thing of note is that here in Michigan, license plate fees are based upon the ORIGINAL MSRP of the car

According to the State, this Turbo cab listed for $42,000 in 1997

so they tattoo me pretty good for that.
