How "bad" is the BMW E60 5-series?

We all hear the gushing praise for the E39 5-series, but I got to wondering:  As a used-car DD, how bad is the E60?  I mean sure, it's got the ugly "Bangle" styling, but other than that?

Trouble spots?  Things to look for? 

since Sept of 2015 i have DD'd a 2007 525xi, automatic, non-sport.  the 525 is the least powerful N52 fitted to these cars, and the "x" in xi indicates AWD.   bought with 136k miles on it.  this week she will hit 200k miles.  reliability IMO has been no worse than i'd expect from any car within that range of age and mileage.

the PO was not a car whisperer by any stretch, so it came with some deferred maintenance issues, which i addressed at my leisure.  here's a list of things i've addressed in the last 3.5 years that are not routine maintenance:

2016-01-30, 143k:  replaced original (electric) water pump and thermostat, replaced gaskets on oil filter housing and oil cooler.  water pump R&R is a motherberkeleyer due to packaging with AWD.  there's an automated coolant bleed procedure that must be run to get air pockets out of coolant passages in cylinder head.

2016-09-22, 154k:  replaced accessory drive belt and idler/tensioner because they were getting noisy.  also replaced both front suspension "tension strut" bushings and both outer tie rod ends.

2017-06-02, 165k:  replaced both front swaybar end links

2017-08-26, 168k:  replaced transmission mechatronics sealing sleeve, changed ATF and filter (which is an integral part of the pan, so instead of a $20 filter and a $20 gasket, it's a $130 pan kit).  also drained and replaced transfer case fluid.   all of these items were on the dealer PPI i got at 136k.

2017-10-12, 170k:  replaced heater control valve and flushed/filled coolant with BMW long-life coolant.

2018-01-28, 175k:  cleaned VANOS solenoids and replaced associated o-rings.

2018-02-13, 176k:  repaired broken wires in trunk lid harness.   cold-work / fatigue failures where the harness has to bend when the trunk is opened and closed.  poor routing caused this failure.

2018-04-04, 180k:  replaced original alternator, also replaced (again) gaskets on oil filter housing and oil cooler.  also replaced valve cover gasket/seals and ran ValveTronic relearn procedure.

2018-07-02, 184k:  replaced original starter, replaced one crumbly CCV hose i broke while removing intake manifold to access starter.  i later learned that starter R&R could be done without disconnecting this hose.

2018-07-07, 185k:  replaced original transmission cooler thermostat, cleaned blockage due to jellified Blue Devil stop-leak from radiator and trans cooler, replaced coolant with BMW long-life coolant.

2018-08-09, 187k:  replaced VANOS filters aka "non-return valves" which are located in the passenger side of the cylinder head, not on the front of the head with the VANOS solenoids.   also cleaned and tested VANOS solenoids, and replaced all 6 COP ignition coils.  Also fixed TPM Malfunction by soldering a jumper wire into the TPM PCB to bypass a broken pin in the connector.  Pin was corroded, with no evidence of moisture anywhere.   poor material selection?  poor interface fit between terminals on PCB and terminals in harness-side connector?  IDK.

2018-12-28, 194k:  Dealer executed NHTSA recall 17V683 to replace heated PCV valve due to electrical short melting the PCV and some nearby components.

2019-02-17, 197k:  replaced (again) oil cooler gasket.

and there's been a couple of ghosts in the machine: the first ghost is in the HVAC system.  twice in the first year, the HVAC fan stayed on when i shut the car off.   i had to pull fuses to get it to shut down.  could not repeat.  hasn't happened again.  the second ghost is in the clockspring assembly.  occasionally, especially in sub-freezing ambient temps, the SWA sensor loses calibration and disables VSC, so it throws a DSC + 4WD fault.  this is cleared by cycling the key and turning the steering wheel full left - full right - back to center before driving off.  it happened 1x in 2016, 3x-ish in 2017, 3-ish again in 2018, and about 20x in 2019.  interweb says clockspring can be disassembled and cleaned.

having said all that, i'd buy another one.  especially a RWD with a manual trans. 

I have an '04 530i that I have owned since 49,XXX miles.  I got it 10 years ago from a BMW dealer off lease.  I am currently at 144,XXX.  I have changed fluids, and some worn suspension parts.  It has been trouble free since I have had it.  Par for the course with all the BMW's as a family we have owned.  We have had 4 of them, all have gone 170,XXX plus miles.  The key is to find a good BMW gnome to work on them if you don't want to do it yourself.  I have an early I-Drive system that is ok.  I plan to keep it till my plates are up in '20, then see what wagons they have to offer.
