Where in Europe can I purchase a car without residency?

The U.K. is not as easy as the People here describe !
I was in England last Year to buy and register a Car, but it is NOT possible without a RESIDENTIAL Address, both for Registration AND Insurance; a Mailbox-Address will not suffice.

I am now in Spain, where my Car expired, and here too Requirements are higher and more complicated than the Information found on the Internet would indicate.
One needs an N.I.E. (Numero de Idenditat de Estranjero), which also requires a RESIDENTIAL Address, AND Health Insurance, AND an Appointment at the Policia Nacional, which can take up to 6 Weeks!
The whole Process is completely absurd and frustrating.

Now I’m considering using this Company in Bulgaria mentioned above by Bob.
I have been in Contact with them to clarify some Questions.

Here are some Problems I see with Registration in Bulgaria:

1. The Car has to be driven to Bulgaria to register it, and it’s a long Way from Central Europe or Spain, and requiring driving through Areas that are not the most desirable.
2. The Car has to be driven back to Bulgaria EVERY Year for the M.O.T., not something I would want to do.
3. Then You are driving around with Bulgarian Plates, which is a potential Magnet for the Police in central and northern Europe, and could attract some discriminatory Law Enforcement. Not something I wish to deal with.

It could and should be relatively easy to register a Car as a Foreigner in Europe, especially now with the E.U. in Place, but it is not thanks to Pencil-pushing Bureaucrats of the respective Countries that need Job Security and make our Lives difficult.

As already mentioned, buying the car is not the problem, but registering in your name is, if you do not have residency. If getting residency is not an option, an alternative could be setting up a company and registering the car on the company.

This seems to be possible in Bulgaria. You can drive around in the whole European Union with Bulgarian license plates. You can even buy the car in another European country and then get Bulgarian license plates for it. There are providers offering this as a service (this is just an example, there might be others offering this; I’m not affiliated with them): they will set up a company for you for around 250€. It will then cost another 500-600€ (depending on the car) for license plates, insurance, eco tax and fees.

I’m sure you can get this done cheaper if you don’t rely on someone else doing it for you. However, I guess this might be difficult without some Bulgarian language skills.

Buying a car is not the issue, really, it is getting it registered in your name. I am not aware of any countries where you can do that. I am aware of two alternatives though. In this answer I will focus on the Dutch side of these things as I am most familiar with them. Note that I am not a lawyer and I may be missing factors.

Option 1: registering as a resident.
This is a lot easier than it might seem, as you only need to be a resident at the time you are registering the car in your name. You will have to find a place where you can register, though. There are a few consequences, like having to get health insurance and effects on government support the people already living on the address might have. The registration takes no more than a few days usually. I am unaware of how difficult this would be for a non-EU citizen, you could consider asking this on expats.se. In case you buy an old timer car (25 years or older), you can then emigrate again without any troubles, as they don’t have to pay any taxes. They do need insurance, though! Getting insurance and then leaving should work fine, as long as you always pay.

Option 2: German export license plates.
This is more of a short term solution, but perhaps suitable for you. If you buy a car in Germany for immediate export, you can get export license plates valid for up to a year. These are (to my knowledge, and certainly in Netherlands) legal to drive around with outside of Germany till they expire. More information (in German) can be found here: http://www.ksm-online.de/.

Added by Dennis:
To add an alternative, the UK seems to be quite relaxed about non-resident car owners (it may be that they assume you are resident but nothing involves checking that) and will register the car if you have a UK address to receive correspondence. Many UK insurers will provide insurance for foreign-licensed drivers only with a requirement that they get a UK license within a year, but there are brokers specialising in finding policies for those who won’t ever have a UK license so this is apparently not uncommon. The downside of a UK car for travel in continental Europe is obvious but buying, registering and insuring one is at least possible for a non-resident with a UK address to use.
