I have no experience with the 4.8.

I have owned a 4.6 since it was new. I have kept it 7 years longer than any other new vehicle I have purchased in a very long time. In the past I would find something that was newer technology and didn't look dated. I still think the 4.6 is absolutely great in all ways. When I do decide to get something else I will keep the 4.6. Any of the newer X5s I have driven, including each year of the X5M have been woody killers.

I see the posts about how terrible X5s are about parts failures. That is so far from what I have experienced. I added all Dinan mods available except the supercharger before I took delivery. Last year at 105,000 miles I added methanol injection and 150 shot of nitrous. The clock is now at 110,000 miles. I upgraded the suspension, I think it was at about 85,000 miles. There was nothing wrong with the original suspension at that point. Other than OCD maintenance I have replaced one radiator hose, an expansion tank and the plastic overflow tube. I have never had to go inside the engine and have the original transmission. I don't like that I have gone through two new MAFs and have had to clean each one since the nitrous addition, but that is a small penalty that is fine with me. I go through tires and brakes more than I would like but there is a reason my tag is Redliner instead of recliner.

The voices in the wilderness of folks that are not having problems with their X are heard far less but this is a forum where most the the discussion is about how to fix something. I say that if they have had all the problems some shout about about without any reason why they still own an X5 they are placing an ad about their poor judgment or they have taken a break from beating their dog and their wife if she hasn't already divorced them.
