I would ask about Rust repair back wheel wells, I would also check the front sub frame for some rust. Also maybe ask if the timing belt, Timing Techiners, timing pullys, head gaskets and intake gaskets were done when motor was refurbished. I also would ask last time oil was changed and that spark plugs it has.
Also u could ask when break pads and rotors were done...
just some simple questions
Good looking ride!
