Turbo Lance empty weight

So I'm still looking at buying a Turbo Lance.

I finally find one I really like only to find out that the empty weight is
over 2400lbs.

The book lists the Turbo Lance at just under 2100lbs.

The panel is pretty much standard plus a Garmin 530 with a few other mods,
but I can't understand where the 300+ extra pounds went. Sure would like to
carry that in pax, bags, or fuel.

Can anyone else relate to what might add on that much weight?


Thanks.
