Send me your name number and address. If I'm not busy u don't mind lending a helping hand. I have a feeling you are going to move right across the top of that list.
Any gloss black should work fine. I know BMW has a specific silver for wheels but I'm un sure about a black. Sand out the curb dings with a rotary tool and use a small amount of filler. Scuff it up prime it and respray.
Looks like they pinned your oil leak to a bad vcg easy fix. Possible water pump t Stat problem. Does the ac make any noise? Hissing or compressor clicking on etc?May just need a recharge.
What I'd do:
Pick up an ac recharge kit.
Buy the vcg change the plugs and check the coil packs while you are at it.
Find that coolant leak before throwing parts at it. But likely it's either the tstat or wp
Add coolant and get any air out of the system. Open up the bleed screw and top off till it starts to come out. Close screw and let it run a bit. Keep your eyes on the temp gauge, If it starts to climb shut it down. I believe on an r56 the screw is on the top of the tstat. If everything goes good start looking for leaks.
Whoops on an r56 it's on the front left side (drivers) of the bay. He is talking about the cap on this tank. It's a sealed system and must hold pressure to avoid boil over
Well honestly you won't know without looking. Check the expansion tank at the back of the engine bay for leaks. Do you have an idea of where the leak is spacially? Drivers side? Pass side? Front or back of the engine bay? It's likely something simple. Warped head is far less likely unless you really ran it hot. If you pulled over right away you should be fine. Check the oil and make sure it's not foamy (coolant in oil). Worst case any competent shop should be able to do a leak down check. Where are you located if you have a driveway I can narrow it down for you.
If you don't mind send me a message with your number. I know you may be allowed. But they may not be happy if I'm there. I have no idea where you work. I'll message you must number text me.
I have fsds in my back seat I need a place locally to install. You can have my stocks when I remove. I'll see if I can find a driveway and a jack asap.
