Buying a car in Germany and driving back to the UK

[AbsoluteZero]

Hello,

So I am about to buy my first car in Germany this year. I have driven others cars for two years and now the time has finally come to get my own.
The car I will be getting will be either a BMW E46 316i Touring or 318d Touring depending which is at the best price.

My question relates to the procedure for getting export plates and motor tax, as far as I understand at the moment I must first buy export insurance here:
https://www.nondos.de/versicherung-kaufen.html?cfc...

Then once I purchase the car go the the equivalent of a DVLA present the insurance slip that I get from the above then they will both issue me with the export plates and allow me to pay one months motor tax. By the way where can I find these office?

Then I affix the plates to the car (which will have an in date TUV) then I can legally drive home.

Could someone who has already been through this process confirm whether this is correct or if I need to do something extra. On a side note I did contact the company above who sell the export insurance and they confirmed that the insurance will coven a 18 year old (me) provided I have a full drivers licence (which I do). Is there any other snags I could run into being the age I am?

Thank you for all the really useful information.

I will more than likely be buying the car used privately, so I guess I will have to de register it as well.

Can I go to any Strassenverkehrsamt to get the plates or are they specific to the exact car I will be buying.

Thanks again

So once I sign the papers for the new car with who ever is selling it I take those papers along with the insurance ones to a Strassenverkehrsamt, and get them to stamp the plates and I go on my merry (hopefully) way.

One last question, can I buy the insurance with the company I listed above, say a month before I go to look at the car?

Once again thanks for all the information.

Here's my plan:
Try to arrange with the dealer /person selling the car that he unregisters the car and ask if he could arrange the export plates and insurance.

Otherwise:

I will go with my friend to buy the car.

Go to the nearest registery in my friends car and get insurance and export plates arranged.

From what I can see the online insurance link I provided will not work for me because I will be arriving on a Friday morning and have to get everything done then.

Thanks, So I would be able to get the insurance on Friday as well as the car and exports plates without any hassle?

Why I am going to Germany to get my car; It has always been a childhood dream to go to Germany, buy an E46 (M3 actually) and drive back home. Crazy but hey
