Eamo's is a good idea. Any rebate application gets a print out that, amongst other things, details the OMSP (although that probably hasn't changed since before they removed them from the calculator - was €85861) and for this purpose the most crucial bit is the Depreciation Code (alpha-numeric in a range of A1 to K2). It doesn't matter what the year of the car is, with these two bits of information you can work it out for any other year.
