I just recently bought this car. I was going to buy a newer LS but saw this car for sale and decided to drive it. I was really impressed. Its handling is great and EXTREMELY responsive. The car has 145,000 miles on it and it runs fine. I probably will only have it for another year, but it will keep me satisfied. I might stick with another Cadillac for my next car.
The engine is very powerful. The sound system is nice, but like the last guy said it's not VERY loud. The seats are very comfortable, even in the back and all the features work properly.
The gas mileage is just OK, averaging almost 17 to the gallon (I guess that is not bad for an 8). It has lots of torque steer, but that is to be expected with a powerful 8-cylinder front wheel drive car.
