@classiccarhubuk: Everyone knows the M3, but nobody knows THIS...V10 🤫💀 You think the V8 M3 was the holy grail of the E90 generation? Hartge looked at it and said: "Hold my tools." They took a standard sedan body and crammed a massive 5.0L V10 inside, creating the legendary H50. This isn't just a garage swap – it's a ultra-rare piece of tuning history that most people have never heard of. Did you know this existed, or did I just blow your mind? 👀👇 #bmwm3 #bmwhartge #h50 #rarecar #v10
