there is a possible solution that would be much better, and that would be to do a single pay lease. This is where you do a lease but all the lease payments are rolled up together and you pay them in one lump sum. At a GM dealership and specifically through GM Financial this can save you thousands. The reason is that you pay interest in a lease just like you do in a loan, but in the case of a single pay lease the lease rate is reduced by 1% for terms of 24-27 months and 1.75% for terms 36-48 months.

Then just wait until the end of the lease to decide if you want to buy out the lease. If the vehicles' market price is less than your residual than it's probably not a vehicle you will want to buy out. If the market price is more than the residual than you buy it out and pay taxes on the buy-out price.

Just go into it knowing that this will likely not save you money vs doing traditional financing unless the lease rebates exceed the loan rebates. My only experience is within a GM dealership and it's not common to see the lease rebates be better than loan rebates.
