the government has come up with this figure...I don't know why its 204.5%, I mean they could just have 200% or 210%, but two hundred and four POINT FIVE !!!! they have it so precise unlike everything else in pakistan...
cars above 1800cc have the 204.5% duty, can be reduced if car is older, 1% per month upto 3yrs ( 36 months ). this percentage is of car's OEM value as capsat has mentioned, but I guess he missed that you bought a brand new accord so 32 lacs must be the OEM price.
e200 is 1800cc. On 1800cc cars, duty is ~$24,000 something. I think shahnawaz sells e200 for somewhere around 90 lacs or so... e250 is also 1800cc so it comes at a little over 1 crore or so...
the same 1% per month rule applies on 1800cc and below cars as well, so you will find used 3yrs old uk spec e200s for ~70+ lacs...
you could also find a prado for 80+ lacs...
and for ~40lacs you get a c180/200....for a little more you get my favourite car Audi A4.
