On the continent, it's left-hand driving on the right side of the road. Also, in the US, many cars are automatics, while in Europe the stick shift is common.
Don't forget the technical issues. There are some differences between European and American cars, even if it's the same model. The blinking lights are different and there's also something with the exhaust (katalysator I think, I don't know the exact word in English).
Last but not least, in many countries you will have to pay some form of tax to get the car on the road for the first time. This depends on the age of the car and its initial cost. This is not the same as the yearly road tax, which can also be expensive.
For a car with that value, it might too much of headache. In some countries (such as Belgium) there is an interesting market of former lease cars, usually only 3 years old because that is the standard period after which they are replaced and sold by the leasing company.
