A new Maico 250 or 320 from the company in Germany is 7,925.00 euro that's just over $10,000.00 AUD.
On another subject I have just got the latest Just Bikes (21/11/2013) and the 1969 Maico is in it again. The price is $3,500.00 there is also an RM 370 A for the same price. I don't know what the legalities are but surely if someone wants to they can force him to sell it for that price (unless he can show it has already been sold).
