The goal for this assignment is to create some classes for a warmup in my C++ class. I have successfully made the showroom class (somewhat...), but for some reason my Vehicle vector is not working. Whenever I try to compile the code, I get an "undefined symbol" error. If you have any suggestions on how I could get this to work, please let me know.

Below is my main class, and the showroom class I made. If there is anything else you need just let me know. I used xCode.
