Powerful, reliable V8

This 18 year old Car has "lasted 10 years" like it should, as the song says. Its still smooth, powerful, and everything still works. The original white paint still looks like new. Of course, the previous owner obviously took care of it, and I will too. Heads turn, when I arrive in this, even tho, Used, I paid about 20 cents on the dollar for what most new ones cost. Sure, I miss the backup camera, the blind spot monitor, and adaptive cruise of my newer cars, but, I fixed the BSM with a small round concave mirror which eliminated that blind spot. I feel very safe in the powerful big car, that gets surprisingly great mileage on the hiway, sometimes close to 30 miles per gallon, with an average of around 27 hiway. Of course its much worse around town, stop and go. The trunk is so large, that a small family could move in the trunk and live there. Well not quite. This model is the "fleet livery" model. I understand that GM put a 3 year 150,000 mile warranty on the fleet models.. you dont want it to break, so that warranty is a vote of confidence. I think a big difference between "fleet" models and the regular Caddy, is the fleet has an oversized radiator, and holds 60 percent more oil. This is important because radiators tend to clog up, reducing capacity, over time, and causing the engine to heat up. Overheating is a killer of engines and this massive radiator keeps it cool no matter what. It also takes extra oil..8 quarts. That keeps it cool, too. It costs a little more oil at oil changes, But that's but its a small price to pay for a very reliable car.


Don’t buy

These cars are a nightmare wish I would of bought something else, I spend a lot of money on this car to find out that it’s only worth 2000 at the most for resale! Don’t buy
