So I drove over to King's Discount Tires and asked them to replace my radiator. It seems that they will be able to get their hands on a new radiator today, so I decide to leave the car there and rent a car to get to work.
Sam at King's suggested to rent from Budget, instead of my usual Enterprise rental, I figured since I've never rented from Budget, I'd see how they compare to Enterprise. Plus typically there's some kind of deal to get a rental from a store that the shop recommends. They took a very long time to get there to pick me up, I guess there was some miscommunication between Sam and the Budget rental place he called.
Now I'm rolling around in a Daewoo Lanos, until King's is done with my car.
