Can someone tell me if it is better to lease car or buy one?

In the UK the lease rules may be different than they here in the States. Here, leases make good sense for companies with small fleets because of tax considerations.

Otherwise leases are troublesome at best. Leases here come with mileage caps - if the vehicle has more miles than the cap the extra miles are taken off the value of the car, generally between 30 and 50 cents per mile. Being 5000 miles over the cap can cost a couple thousand dollars.

The end-of-lease value of the vehicle is a contentious thing that leaves many people swearing they will never lease again. In essence, at the end of the lease the lessee is trying to get the lessor to buy the car back while the lessor is trying to get the lessee to keep the car at an inflated price. And it is often nearly impossible to get out of a lease, with some continuing after the death of the lessee and passing to the estate. If you like being taxed you'll love leasing.
