I've had my V10 for 6 years now, and I've only had the exhaust studs break, which I changed myself and installed headers. I've done the normal maintenance on it and changed the spark plugs at 60,000. I love it. It tows my racecar every weekend in the summer with no problems and gets decent mileage for all of the power it has. I hope it never dies, they don't make them new anymore in the 250/350 platforms.
