I would not lease a vehicle in todays market. Money is too cheap. The only way to go is with special financing. Current rate for SSR, through GMAC is 5.9% for up to 60 months. Just financed one customer on a 2005 SSR, outside credit union at 4.99%. So some of the financing is there, you just have to find it, or have someone who is willing to help you find it.
