Cool !!
That's a lot of questions!
The plate cost about £200 (about $330 back in 2009 when the exchange rate was in my favour!), which is the cheapest you can buy from the DVLA.
A dateless plate is usually much higher but you can sometimes be lucky and find them for as low as £600 ($800). Most people just buy a Northern Ireland plate as they are cheap (also around £200 / $260) and also dateless. But dateless plates in the UK are usually priced around £1,200 to £3,000 ($1,800 to $4,000) for ordinary combinations. But plates easily sell for £10,000 to £100,000 ($13,000 - $130,000) if they are more desirable.
Import costs (taxes) are calculated on the market value of the car if they don't believe the invoice value (i.e. they know a dodgy sales invoice to avoid taxes when they see it!). then if the car type was not sold in Europe you must have an IVA test to make sure things like the indicators / turn signals are not red (unless it is pre-1966), and stuff like that. And if the car is over 3 years old, an MOT test as well.
Then you pay the first registration fee and your road tax (calculated on engine size for non-EU imports, and emissions for cars sold in the EU).
It sounds complicated like that but it's actually quite a simple process, so long as the car meets our basic requirements you can register pretty much anything here, unlike in some countries I know they have very specific import laws. I only had to change the rear lamps to Cobra lamps for the yellow turn signals, install small white side lights to replace the always-on yellow indicator and add a turn signal on my front wings (fenders) for side visibility. Everything else remained the same as I put my rear fog light instead of one of the reverse lights, so no lights stuck on the bottom of the bumper like most US and Japanese imports. (Reverse lights are not required in the UK anyway).
When you import the car, unless you provide your own plate (from another car or bought separately like I did), you are given an age-appropriate plate from the region you live in. You don't get to choose it. (That's only on brand new unregistered cars from dealerships).
The plate law allows you to put an older plate on a newer car (hence why you see a lot of cars with 1930's style "dateless" plates - especially on the top-end cars), or people transfer them within the family, so it is possible to see plates worth more than the cars they are registered to! But you can't put a newer plate on an older car. This is to prevent the car being made to appear newer than it is (possibly affecting the value etc).
For such boring plates, we actually have a really complex system to fully understand! And I don't know anyone who knows everything there is to know about the British registration system!
