The E46 scan was long overdue. The design has been ready even longer. But it's built on a reference model, and our car has different geometry. With 3D printing this shows up: parts don't sit.

Evening, FL backyard. Three days of rain, mosquitos out on the third. I stand with the scanner, dodging a cloud that finds the soft spots. Quick pass, 3mm accuracy.

Why 3 and not finer. The model is already done, the scan is just to fit it. Hand-fitting will happen anyway. The project is one-off. Parts from this scan probably won't go into production. 3 millimeters is enough.

Processing, cleaning. The model isn't perfect, but good enough. We can start.

The E46 won't let designers go. You can count the icons of the early 00s on one hand, and the E46 is one of them, maybe the only one.

I've carried it in my head for years, but you can't approach it head-on. There's too much weight on it for any car designer.

The fool goes straight at it. 99 out of 100 burn out. The hundredth makes it through. The thinker sees the risks and stays put. To avoid burning out and getting stuck, you have to lower the stakes and trick your own caution. I look for a car on the cheap and tell myself it's just an exercise. That way you can start. That way you can later cut.

$60. Yes, I found an E46 for $60, in perfect condition except for a salami slap to the snout. Like a car parked in a garage all week, driven only to church on Sundays. Nobody believes me. My family laughs. But it's true. $60.

E46 325Ci, facelift, 100k miles. Glancing hit up front on the passenger side, most likely a truck. Hood touched lightly, bumper off, right headlight missing. Inside, like new.

Bring it home, walk the front. Right fender, headlight, lower control arm. Arm looks bent. Took it out. Yes, bent.

The E46 is cheaper to maintain than Corolla. Cars like this don't exist. This one exists. New control arm $18. Swap, 30 minutes.

The car flies.

Not an M3, not a 330. A 325. That's the brief: an M3 you'd hate to cut. This one you wouldn't.

Back in the shop. Mustang at the back wall, living out its days. Organs went to the 68 fastback, interior to the 69 chopped Beetle, another body growing on the same bones. On the old one, only the wheels left. 19-inch Volks-like wheels. 10.5 ET+35 Square.

Walking by, I stop. And it hits me: these will work on the E46.

Pattern's different, I know. But an adapter-spacer solves the pattern, and we need spacers anyway: this car is going wide body. E46 bolts into the adapter, Mustang bolts into the wheel. Set the wheel, lower the car. Half a centimeter to the arch. I stand looking at the wheels: nobody would put these on an E46, and there they are.

The Mustang gives. Bread and wine.
