so far high mileage is not a concern for BMs....
more importantly is the preventive maintenance to ensure d car is problem free

my e39 clocked 350,000kms
about 80,000kms on d new stroker kits....
GB still d same ZF gearbox...have done full rebuilt on d GB...
car is still going strong

only issue is now on the windscreen rubber lining....
prolly in a few months time go claim new windscreen from insurance...

one year about 40,000km on my e39....bout 3k km per month...about there lar....
alwiz outstation drive during weekends.....

after ecu remap n everything...power is slightly different from 3.0 on the torque....
i'm using the 528 exhaust manifold different from b30
plus my ecu is d same 525 but did do remapping
road tax still 525 roadtax coz same engine number...difference is only d stroke size....same bore size
wanted to convert to manual but drive in jam abit lazy...hehehehehehe
brakes have to change coz needed more power to stop
moded the 2 pots for d front with zimmerman rotors for front and rear
goodridge sbbh
ebc brake pads

i'm using philips bulb...rm2.50
so far ok..been using it for few years...

bro bizness...ur 523 still 140k mileage?? did u verify the mileage with ECU n gearbox mileage?

i'm not very familiar with m52 engine mods...ehehehehehe

but m54 alot of things can do....

next thing i might consider LSD and lightweight crank pulleys

any taikor here knows where to find a E36 master brake pump controller board?
