My car doesn't have power windows or power lock. I would love to have both power windows and lock without having to get a different car. Is there any way I could get power windows and lock without buying a new car?

I don't think so. Common sense tells me it would be very expensive because they would have to re-wire your car.

Yes. But you need a donor car identical and cheap. Then you need the knowledge and tools to do the swap. Think you can handle that?
