Wheeler Dealers quoted the price as £200 for all the Rangie bits. I reckon there were 8 pieces.
At the other end of the scale a company who do interiors using this for high end cars (Jags, etc.) at dealers or individuals on an exchange and fit basis, charge £400 for the dash strip, 4 centre console pieces and 4 door inserts.
Might give you a feeling for prices.
