Did the semi truck stop?
Was he cited by the PD for following too close?
Who's his insurance company?
Are you injured?

Cold hard truth here. (I do this for a living, so feel free to ask away.)
Your car is a total loss.
The front impact bar is swayed over to the left side by the impact, and your rear impact bar is swayed over left as well. (That is what buckled your left quarter panel, and closed up the left fender so you crushed it when you opened up your door.)
The semi truck is 100% at fault for the loss. When it's raining, you need to slow down. You did the right thing, slowing down is fine in the rain, but he failed to maintain a safe following distance and hit you.
To fix your car, your going to need a minimum of frame setup and about 4 pulls on the frame rack. (These pulls will take some of the damage out of your left quarter panel, but it will not fix your left fender, or the direct impact damage to your right side front and rear.) The cost of repairs will exceed the value of the car. (Total loss in the mind of the insurance company.)
I'm no lawyer, so I can't give you leagal advice, but here's what I'd do.
1) Go to the emergency room right now, and get checked out. Tell them you were in an accident, hit by a semi truck and spun out, and you want to make sure your OK. (If your sore, that's all the better.) Get a MRI or CT scan done if you can, but X-rays at a minimum to make sure you have nothing broken.
2) Contact this semi truck's insurance company and get the claim started now.
3) Start looking for comparable Mk'3s for sale in your area. You may need to look on Autotrader.com and other sites like this to get values of what your car was/is worth.
4) Pull anything of value you want to keep off the car. Stereo and other items like boost control and SAFC's don't add any value in the mind of the insurance company, and you can use them on your next car.
5) Make a injury claim NOW. DO NOT TELL THEM YOUR FINE IN ANY WAY. Tell them your sore, and in pain, and that the guy that ran into you owes you for the loss of your car, and your pain and suffering.
Ok, so now that your ground rules are setup, here's how it's going to play out.
The other guy's insurance company will tell you that your car is a total loss, and it's worth 2000.00 or less. (possibly might be higher, but not much.)
Your going to have to argue to get any value out of your car.
They will offer you settlement amounts on your injury claim based on medical treatment and what the Dr. writes down. (Again, DO NOT TELL THE Dr. your fine, but say you want to be sure your going to be OK, and that your sore if your sore. Don't play act, your going to be sore looking at your impact photos.)
If the insurance company of the semi truck driver says your partially at fault, explain they are wrong, and that a jury will agree with you. You slowed down in the rain, you were proceeding with caution, and a speeding, out of control semi truck driver ran into the back of your car, spinning you out and almost killing you? And your at fault? LOL Laugh at them!! Loudly and explain your ready to get a lawyer and sue if they don't just do the right thing and take care of you and your car.
When they offer you an accepable amount for the total loss of your car, then you can settle your injury claim with them.
Here is how that works.
If your ER visit cost 1000.00 you can generally get a matching amount in "new" money to you, and they pay the ER Dr. bills. (So, by being smart, and working the system, they will pay you money for the pain and trouble the asshole who they insure caused when he ran into the back of your car in the rain.)
Good luck.
Sorry to be so blunt, but It's the best way.
