I currently have 18 1/43rd Minichamps Escort Cosworths.
According to my list there were 36 in total.
But there is also the 1/43rs Schumacher collection one in Red and also a Ford boxed Red one as well as the Amerang one you mention.
So that would make 39-40 in total.
Road cars in original Minichamps boxes
There are
1 x White
2 x Black
2 x Green
1 x Yellow
1 x Red
Then there are all the DTT, ADAC, Belgian Rally and WRC ones.
Be prepared some of the them go for silly money.
The original White and Black along with some of the rally ones now go for over £50 each.
