3 series maintenance is still acceptable as it is the best selling model in BMW range and the parts is quite common worldwide. If your ride is not like hybrid or higher performance ride, usually the part cost is reasonable and some even cheaper compare to Japanese counterparts. Not all BMW parts are expensive and if there is a will, there is always cheaper OEM & half-cut parts to source for after warranty ends. The most important is to get a reputable service center or mechanic to take care your ride as a lot of workshop outside are just ripping ppl off.

Actually 2nd value of lexus is quite good in market for bread and butter models like the IS250 or GS250.
Only when you want to trade in the dealer will koyak your car price so they can earn more money from your lexus.

Still it is a Mazda and FWD. If you driven a BMW, you will know that normal Japanese ride (Except Lexus) still unable to get the NVH, ride and handling of a German marque.

BTW, what kind of oil leak need RM3k? Did your mechanic tell you where & what part to replace? As recently my mechanic told me mostly f30 oil leak is just from the head cover, oil seal which is common areas, the most just change few rubber seal which cost few hundred only and the most workmanship kau kau only around 1k if need to dissemble the gearbox/engine for flywheel & gearbox oil seal.
The only concern for this engine batch is the N20 timing chain guides which will degrade and break into pieces and this is the only higher cost to replace.

FYI, BMW 3 series is D-Segment which is similar to Honda Accord/Toyota Camry category which is also near 200k price segment now.
Civic is for sure way cheaper and smaller size C-Segment category but apple to orange comparison.
