Hi all, I have owned my car now for about 6 months now and have searched and read all of the cool threadsabout different things us owners can do for our cars. At the time of the purchase from the Fitzgerald Mall Dealership I bought the car with 27,000 miles and it is a 07 mazdaspeed3 and I was either suckered into or made the right choice as to buy the extended warranty (whip). Now I am thinking more and more about installing upgrades and new parts that may void the warranty or be too much of a hassle to unistall the parts and installing the original before taking it in to the dealership to get fixed. For example, hearing how the "easy way" to upgrade the exhaust on our cars involve cutting of the oem exhaust. I am wondering whether or not I should keep the extended warranty or call them and take it off my car and have that go towards the principle of the car. I am a very big car enthusiast and would love to do more with the car. I have owned a CRX with a B-18 swap and a 240SX with the Sr20DET (silvia) swap. Ilove the mazdaspeed but cant decide if I want to go through the risks of getting caught with aftermarket parts on the car when i take it in to the dealer. once the after market parts are on I plan on not taking them off, why reverse the progress of the car? well just want to know what the friendly people of the Mazdaforums have to say or think. thanks in advance.
