The Uk spec kit is selling fast over here , the importer had two shipments one of 30 kits and one of 20 kits within the first few weeks of the kit coming out and both batches sold out within a week. No idea how many have come in since i last chatted to the importer but the RDX is proving to be the most popular Corally yet.
Just got to get mine built if i can ever get my partner out of the house for long enough.
