It is reasons like this that people learn to do basic car maintenence themselves. How hard is it to screw up an oil change or air filter replacement? For these guys, it appears to be pretty easy. Make it easy on yourself next time and do it yourself. It involves removing 4 screws, pulling the old element out, putting the new one in, and tightening the screws. Why pay someone tons of money to screw it up when you can do it yourself cheaper and with the peace of mind that it was done right the first time?
