I have two cars I'm looking at: First: is a 2003 Impala, 38K miles, 3.4L, asking 11500, and willing to give me 5K for my trade in. Also has a 4yr, 70K dealer drivetrain warranty. Payments will be about $160/month. Second is a 2005 with 30K miles, 3.4L. Essentially the same car, just younger, for 13,500, and only 4K for my trade in. Payments will be about $220/month. Are there any real differences between these two cars that I should be aware of? Differences between the model years? I'm really leaning towards the 2003 due to the low payment. Also a friend has a 2003 and is very happy with it. Would I really be getting that much more with my money with a 2005?
