when I first moved to the UK- I took the company car package. I figured the convience factor outweighed the additional tax burden. Now that I've been here for awhile I've started to investigate the car thingy more. Something I've realized is that there are two different car related benefits. The first is the car itself and the second is any fuel that you use for personal use but that the company pays for. Also, the specific tax is based on two things: 1- List price of the car, 2- How "dirty" the car runs. The Co2 emissions are translated into a percentage which is then multipled by the list price of the car. For example, my petrol, automatic volkswagen beetle had a list price of £18,000 and the percentage was 32%. My new car is a petrol/electric hybrid toyto prisisu, list price £19,000 and my percentage is 11%. That's just for the car. The private fuel is more.
I've heard things like: If you are the type of person who wants a new car every 3-4 years, it's better to take the fuel benefit. If you're the type of person who doesn't mind what they drive you should buy a car. YOu also have to weigh up how long you'll be there, etc....
