i have a 335d e92-its a 57 plate
seems to be a good fast economical car
havent had it long enough to get remapped or anything yet

i also have a 530d estate-e61 remapped deflapped dpf removed-i like that a lot to drive[doggie transport]

the 6 cylinder diesels all suffer from the same failings-main thermostats.egr thermostats,glow plugs, glowplug control units,flap failure/oil leaks at flaps

the 3 series suffer from light modules and above

if fitted with i drive this can fail

my 3 series has 19" wheels non rft and is a little harsh in the ride
my e61 is an early car with 18" rft and is a little jiggily over uneven roads but this is better on later cars-both mine have bmw m sport suspension package
