I want to buy a 1969 camaro ss convertable, with an engine capacity of 5657cmc3. The car is cheap but with the polution taxes in my country i risk to pay over 30 grant, but if it had euro 3 the tax would cost under 4 grant. Is there any euro 3 kit that can be installed on on the camaro? And if it is, how much would it cost? Thanks in advance.
