I just traded in a 2007 Acura Mdx w/ 96000 miles, never a problem, I just purchased a base q5 w/ heated seats, panarama roof and bluetooth, I love the way the car drives, I just hope I can get the same amt of miles without any major issues, It might be too late to ask but how reliable is the 3.2 and the triptonic transmission, also I looked thru the owners manual, no mention of changing the trans or diff fluid ?, Also can the oil be checked with a traditional dipstick, I found a black cap that looked like a dipstick but there was nothing attached to the end .
