Rented a car for 24 hours.... Hopefully my car will be fixed tomorrow. I hate only being able to drive short distances in jt. Not only that, it's just nerve racking because it's a really old car and I'm not used to it yet. I'm constantly worry about, "whats that noise, is it going to stall" or "is that normal" lol. Ugh. My luck with cars suck
