Oh, didn't know that. Pardon my ignorance. Hard to keep up la like this. This is the only line I'll probably be able to complete. Not really a completist but line up from this line aren't bad that I want something complete for once. 

Not a problem.. I was surprised when they decided to quickly reuse the number too. But since its a relatively new line, completist can still catch up at this point.. but 2 models for every couple of month kinda hurts the wallet... 
The model may be out of rotation, but if its ever re-released,  its usually with a new number and a new design or color. eg. Lancer Evo X maroon and Lancer Evo X British Police.. Older models (Evo IV, VII, R33, R34, etc) are no longer in production when they are replaced.. and as every month a number is replaced with a new model/design/color.. so the 140 models of this month is not the same as a month, 2 months previous..
