I'd like everyone to meet Effie. She is a 1991 Final Edition (FE) Jeep Grand Wagoneer which had 246,000 miles on the original engine when I sold her in 2005. Effie was owned by a family of car detailers and automobile mechanics from 1993-2005. As you might imagine, she was in pretty good condition and was treated with care.In 2004 I decided to spend a lot of time and money on Effie, upgrading the stereo to a CD/MP3 player, replacing cardboard panels with custom maple real wood panels (that I created myself in my garage), repositioning the rear speakers to the rear doors, adding two 6X9's and two 12 inch subwoofers for a total of eight speakers altogether, adding a cb radio and installing a dc to ac converter.The only major component that failed on Effie was the rear end. It was replaced in 1993 and we never had any more trouble. The engine was in amazing condition, even after a quarter of a million miles, and the Torqueflight 727 transmission shifted as smoothly as the day she rolled off the showroom floor.We installed an additional fuel pump in the fuel tank in order to curb the occasional case of vapor lock (it worked perfectly and hasn't locked since). Now she has two fuel pumps.
