N55 vs B58 - which is the better engine long term?
Debating between a F30 340i (B58) and a F30 335i (N55) for a long term keeper. Both in similar condition and price range.
The N55 is proven and I know what to expect. The B58 is newer tech but less track record. Which would you pick if you planned to keep the car for 5+ years and 150k+ km?
Not planning to go crazy with mods, maybe a stage 1 tune at most.
