So recently I've had a load of issues with my e46 320i. It's at the point where I think the engine is reaching the end of its days or at the very least less and less worth it to repair I had a misfire, changed all the plugs and coils seemed OK then misfire again its at around 240k miles. Haven't taken it in again as I don't know what it is now. I was planning on a m54b30 swap but don't know if its worth it anymore. There's a few cosmetic and other things that are needed to. The big thing is I really want to keep the hellrot color one of the big reasons I got it. Odds of finding a 330i hellrot with a sunroof are pretty low. Although I just started looking. Posting here just to get some advice, should I try to swap and fix her up or cut my losses. I can admit I'm overly sentimental about it. Anyone had a similar situation or any advice would be appreciated.
