My GF's radiator blew and the stop-leak crap worked for a little while... Once it started leaking again I decided to just replace the damn thing... Googled for her year/make/model and radiator... www.radiator.com came up... It has a cheesy interface that acts like you are chatting with a mechanic, but it's actually timed to prompt you for generic information... Anyway, I called the number, they quoted me a price pretty much on par with what all the other shops in the area were going to charge, but they offered same day delivery. Within two hours there was a guy at my door... Hell they even threw in a little bag of miscellaneous candy!!!
