A/C gone, heat might be going next.
When I got my car, the A/C worked but was weak, and was R12. I don't use A/C much at all. So, rather than retrofit a system I never use, I deleted it. Besides, I took A/C off my old mustang and never regretted it A/C only draws on the engine, clutters the engine bay, heats up under your hood, less radiator options, and most of all, weighs a lot. When you take the A/C off your car and pick the system up, that's a lot of weight hanging over the front wheels.
Heat, might be going next. I never really use it, even in winter, but the car doesn't get much driving in the cold. Yet another thing that clutters the engine bay, less waterpump options, and once again, ads weight. Of course to remove the real weight, the whole HVAC box would have to go.
My car is not a daily driver, I have my Chevy P/U for that. It's being set up (very slowly) for a kind of street/strip drag setup, and weight reductions so far have made a huge difference in this car.
