I've driven and owned many cars but I can say that even with a near mint E39 M5 in the garage I still love getting up and driving my E53 everyday. I've owned 4 of them now and each time I sell one I never find anything that I like more as a daily driver so I get another one and hopefully my 03 4.4i will be a keeper for a long time to come. It's been very well maintained throughout its life and I plan on doing the same. I seem to put more funds towards the E53 willingly than the M5 for some odd reason.
