CIF price of 1.6 million is the depreciation in the UK. I'm guessing the CIF for a 2007 C-Class would have been atleast US$25,000 when brand new. According to the depreciation table given by SL Customs (refer: http://www.customs.gov.lk/mv/mvpg02.pdf) the CIF price now would be US$19,250 (77%). I believe the excise duty will be calculated as $19,250 *150% (not on the actual price you paid - 9,500 sterling). Then there's also other tax components - VAT, Port levies, environmental taxes etc etc... I'm thinking the price will be close to 6Mil landed - still not bad considering what they used to cost...
