Thinking of buying the 2005 Cadillac STS?

No 2005 Cadillac STS is for sale by CarmaCars at the moment; this page helps you judge the car before you buy one elsewhere. For anyone shopping for the 2005 Cadillac STS, here are the facts that matter.

A buyer's checks

Ask the seller for the service records of this exact car. Check whether every recall was done, by the VIN, before you pay. A pre-purchase inspection at a shop you choose is money well spent. Look at the tires, brakes and battery; they are costly to replace.

The numbers in plain words

Its 3.6L 6-cylinder drives through a 5-speed automatic. It runs on regular gas. Rear-wheel drive gives balanced handling; in winter, the tires make the biggest difference.

It is rated 13.1 L/100 km combined: about 39 litres every 300 km. Driving 300 km costs roughly $60.93 at our price setting. The EPA estimates US$3,700 a year in fuel for 15,000 miles.

Best uses

It suits a family trip where everyone and everything fits in one car. It suits a weekend away when the train does not reach where you are going.

How big it is

Its car body is low and settled, with a separate trunk. Length: 4.99 m. Check the size of a tight parking spot. The trunk holds 368 litres by the EPA's count: about two large suitcases and a few soft bags.

A longer test drive

Nothing is charged until we confirm the rental and you approve the offer. Rent the STS for a week, or up to 365 days, before you commit to buying one. A week of your own driving tells you more than a test drive: the commute, the parking, the fuel.

Choosing the right one

Write down the VIN of any car you consider; it unlocks the recall and service history. Within the 2005 lineup, trims share powertrains or differ in equipment; the trim pages show which. If two trims share a powertrain, the difference is equipment, which you can check in person.

Running costs

Ask what a set of tires costs for this trim; sizes and prices vary. A 1,000 km month costs roughly $203.10 at our price setting. The EPA estimates US$3,700 a year in fuel for 15,000 miles at US prices.

Over to you

Ask about renting first, and buy with a clear head.

Rent it for a week before you buy

A week of your own driving tells you more than a test drive: the commute, the parking, the fuel. Rent a 2005 Cadillac STS from us first.
