I've found two E39 M5s that I'm interested in. 1. 2000 / 34,500 miles / $33K 2. 2003 / 47,000 miles / $40K Both cars in California and are loaded. The 03 has some upgrades (audio, shifter, sway bar brackets) and is listed here The Yard Sale. So what's more important for a BMW that has lived in CA; age or mileage? I'm pretty sure I can get the 2000 down to $30K-ish as KBB for that car in Excellent condition is $31K.
