I have an 06 Mazda3 that I bought off my neighbor. 252000 miles and still runs great. Not a fast car by any means. Tops out at about 80 in 5th at 3300rpm(ish). Is that normal? I've had it about a year and everything is stock. I bought it as a commuter since I drive around 80 miles a day. Hoping to find some safe mods to maybe get a little more power out of it.
