well i'm not a heavy driver, i barely put 5K per year, so i hope it will hold up together until it hits 150K (time to be sold) so i won't mess with the transmission for the time being.
the spark plugs were replaced upon purchase.
Well yeah, the problem with oil leaks is the labor... the seals are peanuts, but to reach them is a PITA... i replaced the oil pan gasket, it was a 15USD part, but 6 hours of labor!
Don't worry, the wifey will love the X5 no matter what... it's one hell of a cigar lounge running tall and hovering over the other cars with supremacy and prowess
by the way, my wife had a rav4 as well, now got the MB C300 (w204) 2009... cute car overall, smooth and classy.... bouncy a bit on the sport suspension... bah, it's not a BMW!
