i worked on my friends today (indash Tv/Dvd player) looks sweet,but anyways ... a few questions do the motors have the problems with blowing out the spark plug out of the motor like the lightning? how is the gas miles on the highway? and what are any known problems if any ? i was considering buying one for a daily driver but wanted to find out some things before diving into it... i want the 4 door supercharged version .and was wondering if u can find them for under 30k ? thanks guys
