Free: Heater core + blower motor
My 110 used to live in Chicago, and the previous owner installed a rear heater in-line with the normal heater core. It does keep things nice and warm, from the lows in January to the sweltering heat of August (no bypass valve). Not really desirable in Austin unless you're thinking of starting a portable sauna. Free for pickup in Austin or $10 + shipping if I have to ship it out.
