If you get the matching LCM for the cluster then You won't have a tamper dot next to mileage. I have an older cluster in my car 2001 m3 cluster and it works just had to run a separate wire from the LCM to the cluster plug to make sure it back lit correctly with the parking lights.
I'll have a parts car soon 2003 m3 with a cluster that has 136k miles. Probably sell it for $150 or $200 with the matching LCM.
Of you have someone selling both for 160 then that's a good deal and you should consider it.
