I have an extra Passport 8500 which has never been opened. MSRP is $339+tax.
Figured I'd offer this to fellow M3 owners, as it's just a matter of time before we get caught speeding
. This is the best bang for the buck, as this is the black gen 2 version which uses the same lens/detector as the 9500 which sells for $450. The only difference is that this doesn't have gps, which is not a big deal since you'll end up knowing where the false alarms are anyway. Available for local pickup or I can ship it. The box isn't too big, so I'll estimate $10 for shipping.
Thanks for looking!
