The main issue is the damge underneath the car, to the sub-frame and suspension in the front.
As Brent correctly said, the back end went out and the nose grazed the concrete dividing wall between the carriageways, but when the wheel hit the kerb it launched the car up onto the top of the wall so it slid along the top of the wall with the front wheels either side.
I'll see if I can find the photos of the damage before they stripped it down.
You have baby baffles, this is what you need:

But of course just get aftermarket baffles and weld them in to your existing sump.
And B32 pump has dual pickups, you need that too.
I took my old Car Folie carbon supreme tint film off last week as I've never really been happy with it (mainly the application around the rear glass which I had Seth remove after trying a few things). It just didn't look great having side windows tinted without rear.
After sitting in the sun for a day it was enough for me to get some new tints put on today by Nick at Autotintz. Holy sh*t stuff driving a car without tints in summer.
On his recommendation I went for super-reflective silver film - I stuck to 35% because law. IMO the lighter colour really suits the combo I have going on.

I'm honestly furious.
I spend 2 months looking for a 328i manual coupe, offering anywhere from 9-10k for really nice ones.
I settle for an nz new auto and manual convert it, total price roughly 7500.
2 weeks later this pops up, along with a couple of other really nice ones, well below what I was originally offering.
Murphy's fkin law.
Common problems? Many, sadly, on the N42.
As Nathan said, the early E46 got the M43 TU engine. That one is a good 'un - not so exciting to drive, but reliable, simple to work on, and very economical.
E46's are good cars but avoid the N42 and N46 engines at all costs.
The earlier E46 318i had the M43 engine which is fine.
The six cylinders are by far and away the better engine though.
Time to update the concept touring with a major repower.
Out with the S54 and in goes a S65 with M-DCT.
Time for Quest fabrication to do their magic,especially with headers to be fabricated from scratch.
First photos show the S65 and DCT in place.
So far we have custom made engine mounts,gearbox mount and steering shaft.
