I know it's an old thread, but thanks so much for the options you've mentioned! I was browsing car forums to find the best solution and have never thought about one-way rentals. I mean I always wanted to buy a classic car and I know it's way out of my budget and maybe I just have a middle-life crisis, but I can't help searching for Mustang 1967. I found a few used cars that are affordable but I'm worried about transportation and scratches. Some of the companies provide insurance, but it's an extra expense, so that's a dilemma. I also checked the website
