After today's announcement we could politely say that the used KF market has gone a little soft!
Oh how I love 12th scale - buy a car, use it for three or four seasons and it still has a value up to 50% of a new one. Associated and CRC cars come out about every three or four seasons with a pocket-money upgrade or two between, and even Xray manage to make their 12th cars last a couple of seasons!
New KF looks really good quality design and engineering for your 300 notes...
