i just joined last night. my friend told me about the forum but he doesnt own a toyota. i used to be into jeeps, still am, but i just got a new toyota tacoma 07' 4x4. its awesome so far! i want to do some mods soon, but i have a 7-year warranty, and was wondering what you guys/gals knew about NOT voiding the warranty toyota offers??? (engine-wise). my name is richard. i live in san luis obispo but i am from los angeles.
