Is it a LS or a LSE?
 

I'm looking at purchasing a 2002 Grand Marquis. It is either a LS or LSE model. How can I determine which it is. The VIN # doesn't seem to be of any help.

This may not be valid for your year car, but when I was shopping for Grand Marquis last year, power passenger side seats were only available on the LSE.

Best of luck, Bill
