I continue to be very pleased with mine and have suffered no issues other than a broken DVD drive (for the nav system) which was replaced under warranty. And although I don't know for sure, I suspect the 3.0 version could be more reliable than the 4.8 one. Bottom line: I would recommend this vehicle to anyone interested in a BMW SAV and especially if available for a reasonable price!
