Love my 4 cylinder to death. Will not part without it. I recommend a 4 cyl over a 6 anyday due to the fact their easier to work on. If your going for a V6 get a SVT, otherwise go for a I4. My I4 auto is a little slow, a I4 5 speed would be great. Can't really comment on the waterpump issue, don't know if mine's been done. The only thing that's happened to mine that you might want to watch for is pull a spark plug and make sure no oil is around them. If their is it's the valve cover gasket, which is releatively cheap.
