I see that Sportcraft Cars of USA now have a pre-order price list for
Carrera Digital and the prices seem to be both up and down for various items compared with the Euro prices provided by Thomas above. I guess it remains to be seen where the prices will eventually settle.
Contrary to other people's opinions, I think the price of the Lane Changers is VERY high at €42 (around £29) apiece, although the USA price is showing as $35 (around £21). I am assuming you would need 2 x right-hand LCs and 2 x left-hands as an absolutely bare minimum to permit a single lane change in either direction. At Euro prices, that would be nearly £120! It's not yet clear exactly what you will get in a set, but the set looks as though it will be MUCH better value for money than buying the LCs separately.
