2000 Ford Focus with 30,000 miles. Differential blew up and destroyed the transmission. One year ago the struts had to be replaced in the front end. I understand these things are not normal occurrences especially with the amount of driving I do. I can't sell or trade in the car without repairing the transmission, estimate: 2,700.
