New furnace in my car

I’ve been driving the same car for a week 12 years at this point… My parents got it for me right when I graduated from high college plus it’s been a fantastic car for me; I really love this car plus I never imagined that I would have to get a up-to-date one, but I guess today might have come, last month when I got in my car I observed that the a/c wasn’t working anymore, so I took my car into a local HVAC mechanic store to see if she could help me repair the issue. The HVAC specialist that was working on my car told me she didn’t guess it would be worth it for me to substitute the entire HVAC system in my car since the car was so old, then after talking with the HVAC specialist for a while she told me it would be a couple thousand dollars for me to substitute the entire HVAC system in my car. I had to agree with him when she told me this because I also didn’t guess it was worth it to spend that much currency on fixing my car when it was sold. So I guess I’m going to have to buy a brand up-to-date car. I’m not really in a spot financially where I can afford a up-to-date car, but I also don’t guess it’s worth it to put currency into a car that is so seasoned but I’m going to have to buy a up-to-date one eventually, hopefully in my up-to-date car I will be able to get a brand up-to-date heating plus cooling system so I won’t have to worry about this in the future.
