Forgot to add:

If you've owned it for more than 6 months no VAT to pay or if you are getting it new have it marked for export and claim the 20% UK VAT back simples

The very first year you arrive in Switzerland you can continue to drive your car with NL plates and NL drivers license. But before this first year expires you must apply for drivers license change otherwise you will be forced to go in drivers school.
At the same time your car will already be in your possession more then 6 months a and you can apply for import.

wrong!! the import 'clock' is from the issue date of your permit not from when you decide to import it.

This is what I said - before the first year of living in CH expires.

not sure what your tying to say to be honest!

you have to have owned the car for more then 6 months from the date of your permit, so living here a year then importing the car will make no difference, you'll still have to pay.

Vehicle owned for less than six months
If you have owned your vehicle for less than six months, you will have to pay import duty when importing it to Switzerland. You will need to provide official documentation confirming the value of the car and its country of origin, and possibly a certificate of compliance.
You will be subject to four taxes:

1. Customs duties based on the weight of the vehicle and engine capacity. So be sure to remove all baggage and non-standard accessories before the vehicle is weighed. For example, the owner of a 1,500-kg car with less than a 3-liter engine capacity will pay 210 Swiss francs in customs duties. A 2,000-kg car with more than a 3-liter engine capacity will cost 300 Swiss francs. Motorcycles pay a set duty of 37 Swiss francs. EFTA countries are exempt from customs duties.
2. A consumption tax amounting to 4% of the vehicle's worth is collected on all vehicles.
3. 7.5% VAT is also added for all vehicles.
4. And, finally, a 15-franc fee is charged for the report (13.20 A), a document required for vehicle registration in Switzerland.

Vehicle owned for more than six months
If you've owned your vehicle for more than six months, it is considered to be part of your personal effects. You simply have to fill in a clearance request form for moving purposes and it will be exempt from import duty and VAT. You have the right to drive your car with foreign plates for a maximum of one year. The car is reserved for your personal use and cannot be loaned, rented or sold to a third party in Switzerland for a period of one year from the import date. If you do not comply with this condition (by selling your car, for example), customs will charge you retroactive import duty. The amount is determined on a sliding scale according to the age of your vehicle. Make sure that you are legally insured to drive in Switzerland during this period.

About a month after you import your car, you will receive a letter from the motor registration office advising you that within a year your car will have to pass the official motor-vehicle inspection. The proper authority for this inspection is your canton of residence. Each canton has an Automobile Service that conducts technical inspections and issues vehicle registrations.
If your foreign plates are temporary and non-renewable, your car has to be inspected to obtain Swiss plates.

Once the test is done, you will have to pay the Swiss road tax, which is anywhere from 100 to 700 Swiss francs depending on your engine capacity. You will also have to pay for insurance and license plates.
However, you will not have to pay any import duty whatsoever, as long as you do not sell your car within the first 12 months following its import to Switzerland.

I know, I've actually imported a car into switzerland

I read at the other threads that the VAT paid in the country where the car was purchased can be reclaimed when it is imported to Switzerland. Is it true for any car as long as I have the invoices to prove that VAT was paid?

You will have to ask the people you bought it from, as it is they who would need to refund the VAT (not the Swiss).

However, if you have been using the car since it's purchase, then no.

Like s2lemans said, it's probably too late!
You had to buy it when you were in a position to "export" outside Europe: You would live in Switzerland at the time, and you specifically ask for "tax reclaim".

I don't know your situation but looks like you want too much, too late.
