What's an expected cost to soundproof, new carpet, rebuild seats with
leather? Headliner and side panels are fine.

Anywhere from $800 to $3000, depending on the shop.

I just had mine done in leather, new side panels, carpet, everything, done
for less than $1000. (See it at http://alexisparkinn.com/new_interior.htm )
However, it took over a year to get done, and we're friends with the guy who
did the work.

Other estimates were much higher.
