If you run a business it makes most sense to lease it as you can charge it fully (or half if car is also for personal use) to costs. So you get to deduct the VAT and strike some off the monthly income tax. So the car ends up costing as little as 2/3 of the price paid. You can also go the long term hire route where you get to strike it fully off each month since there is no differentiation on use. These deals look similar to lease where you can buy the car at the end of the period but you enjoy a zero deposit and your only worries are putting fuel in the car, the firm that owns it must take care of all repairs and servicing, something you need to do if leasing.
