15 years ago when I changed my cheap Hondas, Nissans to 2000 Maxima. The 200W Bose system in that Maxima was so much better. I was so happy about it...
A few years later I also changed to some better cars which came with better Bose and Mark Levinson systems. However I never became as happy as I was in Maxima again...
PS: I agree the sound from ML system has more layers and sounds better at high/mid frequency than Bose system...
