Semester abroad / reliable US car / purchase advice

Hi, I’m in California from August for half a year and would like to buy a suitable mobile kit for the period. The offer is very large. Can you call me a few “cool” vehicles, which are basically very robust and offer a good price-performance ratio especially on the American market? My “dream car” would be a slightly older Ford Mustang (I know how uncreative ), but can also be something more exotic. I want to be more than $5,000 nic The vehicle should be sold again at the end of the stay. Maybe someone even knows a trusted dealer from California…? I look forward to your suggestions and tips!
