Annual Depreciation is an estimation of what your vehicle's value might be over time based on an average of similar vehicles.

This is not a guarantee of actual depreciation. Local weather conditions, market factors and driver performance will also impact your vehicle's actual depreciation.

2009 Cadillac STS Sedan 4D Standard Features
2009 Cadillac STS
KBB.com Review
If you like the edgy styling of the CTS and XLR cars, you’ll no doubt like the 2009 Cadillac STS. It has room for five, a massive trunk and a long list of electronic features and gadgets.
The 2009 Cadillac STS’ styling has been seen before, namely on the CTS sedan. It does not stand out like the BMW 5 Series or Mercedes-Benz E-Class, and buyers at this level often prefer a more distinctive vehicle.
