I am for the most part! Quite a tribute to them that they are so durable. It has not been easy, or all that cheap - I've have four transmissions and a good bit of other expense (power sliding doors, cats, EGR, power stearing total leak recently) but definitely worth it I feel. Just about all my friends and relatives don't understand though, why I would keep it so long. I don't think I have ever had to do any ecxhaust work other than deal with the bogus P0420 cat codes that cause it to fail emission inspection.
