Your syntax is badly munged, try this:

<div tal:define="results python:here.listProducts(type=request.form.car_type)"
 >      tal:replace="nothing">stuff</div>

cheers,

PS: You can only use one types of TALEs expresion at one time, you were 
originally trying to use a mix of python expression and string substitution 
expression syntax at the same time.
