The hpfp issues are long gone now. And any engine that had it, chances are it has it replaced under warranty. Injectors are the same thing.
1 series are known for the tail lights failing, but again warranty and probably replaced
135's are a great car. Probably one of the few cars I would buy is a 135 m-package 6spd. Amazing car and pretty reliable when taken care of. Main thing with the N54 and N55 is oil changes, if you keep up on inbetweeners (10,000km) you won't run into the carbon issue that negligible owners see.
Performance wise, Dinan stage 2, Cobb or JB, it will run with a M3 (e9x) no problem.
