 The 2006 Mustang v6 Coupe is my 7th Mustang, I bought it new off the lot, and it's left me stranded all over town--thank God I have roadside assistance!  After two years of ownership a dead battery left me stranded out at work at midnight, in March I'll have had the car 3 years and I just had to put a new transmission in it at 68,000 miles. The Ford dealer said that since I hadn't had the transmission serviced at 30,000 mile intervals like the manual says I need to, they can't help. I've not had the oil changed exactly every 3,000 miles, does this mean the engine is going to blow?  Very poor quality.
