I had 2 Caprices - an ex-cop car and a wagon. Both were equipped with the now- legendary LT1. My Cop car was purchased with 58K on the odo and the only necessary repair during its life was a starter which was cheap and installed in less than a half an hour. Car was bulletproof and with the plethora of bolt-on aftermarket parts was an absolute blast to drive. Engine was flawless and never leaked, missed or failed to start. My wagon, after being beaten for 90K miles road like a Caddy with a simple, $600 overhaul of the entire suspension. My buddy's Caprice has over 220K on it and the valve covers have never been removed. Superb cars that GM should've kept refining.
What can I say? It's a Caprice! I've had mine for 3 years now and put 45k mils on her. It's been very reliable so far minus a few little electrical issues. This car has never broken down on me and left me stranded. The L99 (4.3L)which is identical to the LT1 (5.7L) but with smaller stroke and bore is very adequate for city driving especially with some power programming. Gas mileage is very good for a 2 ton vehicle.
Looks great, cheap replacement parts, very comforatable. Takes well to a wide array of mods.
Improvements? That's a moot point considering they don't make these babies anymore. It's got the typical mid grade GM plastic. Some other folks have issues with the optispark distrubutor common to all other LT1 powered cars.
After reading everyone else's reviews, I realized how lucky I am to have this car. I could use the extra cash and thought about selling, but now I see I would probably regret it later. I have the police package too, and anytime I would take it in for service, they would say, "Well you have police tires" or "Police brakes are more expensive". It just makes the car all that much more interesting. Very reliable car, and I look forward to keeping her for many more years to come.
"Special suspension" from the police package, the body, and the great Heat/AC system.
