Hi, I want to take a car to Bangladesh from UK as I am using one since 6 months. What would be the tax?

I am a student in UK. Studying for almost 5 years. Now I have a car which I want to take back to my country. The car is on my name for only 6 months and country of origin is UK, ie, Jaguar, 2005. Can I take this car with me when I leave UK forever? However, my concern is also with Taxation. What percentage of tax do I need to pay for that? Any help would be appreciated. Thank you.
