I think you're right. I have a friend that has burned the clutch out of every car he has owned. He'll rev the engine to 3 to 4k and slowly release the clutch. I tell him that is why, but he refuses to listen.A manual transmission will ALWAYS, ALWAYS, ALWAYS, outlast an automatic transmission.
The only problems with manual transmissions are the operators.
You can be hard on your car and still drive it properly.i have number 66 xb ever made in the world, and its a manual, and i have over 48,000 miles on the original clutch without any problems or slipping, and i'm HARD on my car. maybe the people who's clutch burned out early drove like grammas
