Hey everyone,

Looking to buy a car in the next 12-16 months and want to get a head start.
Previous BMWs are a 2007 335i coupe and a 2009 650i coupe (current).

I am looking between a 2014 and up 435i/440i gran coupe or 640i gran coupe. I drove a 650i gran coupe and it felt big and heavy (which it is). I have not driven the 640i, but was hoping the smaller/lighter engine would help it feel a bit more nimble. Is that the case? I drove the 435i gran coupe and liked how it drove, but liked the interior on the 650i gran coupe much more.

With both of my previous BMWs, I have had a large amount of problems (especially the N54 and oil leaks, turbos, HPFP) and want to avoid those issues in the future. I have read a lot of issues with the 650i, but not so much with the 640i. Is the N55 reliable? Does it have oil leaks etc? I am looking for around 40k miles and will probably keep it until 80k miles, hoping to keep maintenance to air filters oil changes etc no expensive gasket changes or turbo replacements.

I appreciate any feedback that 640i gran coupe owners might provide (or even someone who went from 435i to 640i)
