Simple: Phone them and say you are entering the car trade business. You'll need to fill in a form and buy a year's subscription and they'll happily sell to you. They won't ask too many questions. If you don't want to call them they usually have a rep at a small stand at many major car auctions.

For CAP, ditto.

Afraid I am, Mapmaker.
No need to be paranoid, and quite take some of your points, even though I may not agree with them all. This government in particular seems to have taken the UK from being a country where essentially everything was allowed if it was not forbidden to being a place where everything is forbidden if it is not specifically permitted. You personally may or may not have voted for them, but enough people did. If you (and I mean you as in society) don't like it, vote for someone else.
As far as Terrorism checks go - it's actually quite a lot of hassle to set one up. It needs to be a specific area and authorised for a Terrorism check. I have no idea where they are, though there are a lot in London. It essentially gives police the "random" stop power that we do not have for anything else. In reality though, as others have said, if police want to stop you, there are a number of powers that can be used to do so in a non-random way. It has always been so - back to the "sus" laws and further back during the 20's, 30's and especially the war years. Things aren't really any worse now in that sense than they were then. It is simply public perception that makes it so - added to the fact that we have to be more accountable now, and that means being more formal/filling out bits of paper etc. The traditional "mind how you go" is now a form called a GEN164 that takes (apparently) 7 minutes to fill out.
You will not get a Terrorism check set up to allow you to trawl for other non-terrorist crime.

At a guess, most CVT transmissions are built into Japanese cars, and they make them in the millions. Manuals are rare in the Nipponese home market, so they must be reaping the benefits of mass production. Above a certain threshold, I doubt that further production numbers will markedly reduce unit cost. So, unless the CVT is much more complex, I'd imagine the selling price to ye olde punter in the UK depends more on the "price the market will bear" than a true reflection of the production cost.

If it will physically fit, there should be no problem.

Remember quality is as important as quoted output when dealing with batteries - lots of cheap rubbish around, some at high prices in big-name outlets....

The miles remaining is VERY dependent on the the throttle setting at the time. It

does not base the 'Miles to go' to the long term recorded consumption merely the

last few minutes!
