L-series, GL? DL?

I bought a "L-series" wagon, 1/93 model. This must be one of the last of this series that left the assembly line. When I applied for an insurance they asked me if I had a DL, GL or some other "L". So now I wonder what it is. How can I found out? The manual only refers to "L-series" and unfortunately this is the only information I have about the car. Thanks Ron
