Leasing is good only if you are not going to put too much mileage. I don't suggest anyone to lease if you are living in the crowded city like Boston or Ny due to the fact small accident, scratch on the car is normal in the major metropolitan cities. Most leases allow you between 10,000 to 12,000 miles per year...keep in mind will that be sufficient for you. The lease is ideal for someone who likes to drive a new car every so often, does not mind spending money, and does not care about building equity on his/her investment. You can lease BMW or Mercedes for about 400 a month for 24 or 36 months in our area. Dealers prefer that you lease instead of purchase because they make decent profit from leasing.
