new to x5

[stanE53]

hello,
I just recently got my hands on a 2005 X5 3.0i black sapphire with 117000k on it. so far I have only changed the oil (Castrol 5W30 full synthetic+mann filter) and I am going to replace the intake boot on the throttle body (part gets here tomorrow) which looks to be fun. the X5 seems to have a bad reputation for being unreliable and expensive but so far this is one of my favorite vehicles I've owned. is there any validity to the claims that the X5 is a mess or is this just chatter from people who don't know any more about cars than "right pedal=go and left pedal=stop" or am I missing something? I have owned lots of German cars VWs and Audis and I found them all super easy to work on and I didn't think the parts were all that much more. this M54 in my X5 is a beautiful engine you just have to take care of it. I'm glad to be a BMW owner and look forward to being part of this community.
