Hello Mafia!

It has been a hot minute since I posted. But the feedback here has never let me down. I'm sure threads like this already exist, but the advice for my situation would still be appreciated.

My ZHP is about to hit 160k. Still love the car. Still my daily driver. Car runs like a champ. Very little work left to do on it besides differential mounts. Still enjoy working on the car myself. Still get strangers at stoplights and gas stations asking me if I want to sell it. I really don't want to sell it. At the same time, I do want an upgrade.

I want more power. So here is my question: sell it eventually and get...maybe a 335? If I buy a new (used) BMW, I'd probably want to get something on the newer side, which I probably can't afford yet.

Or..maybe invest in some real performance for the longer run for the ZHP? Investing about $5000 would get me an upgraded exhaust, SC and better suspension. Or do these things hurt resale value at all?

Interested in getting some takes on this.
