That’s not depreciation, that’s discount. These things do not depreciate like you think they do. Example: 2006, a 2003 (3 year old) Denali with a $50k sticker could be had for $15-20k. In 2012, a 2007 (5-6 year old) Tahoe LTZ with a sticker of $50k could be had for $20k. Fast forward to today, a 2 year old Tahoe LTZ with a $70k sticker is still $45k. I wouldn’t call that much depreciation really. Especially when you look at what 2007 Tahoe’s are still pulling to this day. Used car market is so screwed up and over priced. Unfortunately we have nobody to blame but the dealers for dumping so much into them but more so ourselves for settling to buy these things.
You also have to figure sticker price vs sell price. If you pay MSRP for these, you’re stupid. Go to another dealer. You almost always get them discounted anyway. So when you look at the discounted SALE price vs what it’s worth on the used market, they don’t drop hardly at all. New is the better buy if you’re looking at a 1-2 year old vehicle with low miles.
