I bought the car used in 2000 with 68,000 miles. My wife hauls the kids around and we all pull a travel trailer with our Caprice. I have the 5.7 liter engine that is great. I perform regular maint. and have had no major problems. For the flexability and the capability the wagon is hard to beat. It's too bad they are no longer produced. Leave it to GM to Kill a winner.
Reliable and powerful car capable of carrying 8 people as the car has third row seating. The fact it shares components with other b body gm cars mean repairs are easy. The seats fold down to give 8x4 ft of cargo space. And carrys full size spare and Jack internally. This car combines the versatility of a mini van in a cooler package
