If it is a typical lease/purchase such as Volvo finance, then purchase is usually the best deal. However, on occasion sellers will sell to the leasing company for less than they will sell on the market. Also, sometimes the leasing company will use a below market interest rate to make themselves more competitive. You need to be careful though, in some jurisdictions both the lessor AND the lessee end up paying personal property tax, this can be a killer. You need to pay close attention to the residual value being used. In some leases, you are responsible for any shortfall on residual. Usually the best way to lease for personal use is to use a 36 month lease with a guaranteed residual value. At the end of the lease you can exercise the purchase option and buy the car. This can work out pretty well if the deal is good to start with. I have leased cars for much less than I could purchase them, when the situation was in my favor. Work the deal both ways and take your best shot. Since it's for personal use, not business, the tax implication are negligible except for the personal property tax issue.
