I have a 2004 CVPI.
The only three issues on these cars that I know of after considerable research and experience are:
1. The fuel pump, which apparently goes at 200,000 miles (who can complain?).
2. The intake manifold, which may start leaking coolant that drips into the spark plug holes and causes misfiring, at about 100,000 miles. (Make sure if you replace it that you order the one from Ford Racing ($200) instead of from Ford ($650) as they are the same).
This is the only defective part on these cars. All 4.6 SOHCs have the same issue. The plastic cracks, and the new aluminum crossover upgrade will not save you (there is still plastic under the aluminum). Why Ford never properly fixed it is open to conjecture, but I suspect that it is money.
3. The thermostat bolts can seize in the aluminum heads, so always use anti-seize on the threads.
Otherwise, they are unusually reliable cars, safe, powerful, smooth and great on the highway. I get 21 mpg, 0-60 in 6.2 seconds, and great handling.

Re: Buick 3800 vs CVPI -- I own a 2001 Buick Regal Supercharged. Car is a bucket of bolts. Suspension, head gaskets, electrical, it's had about every problem. I just bought a 2004 CV LX Sport. Pick it up in one week. Can't wait.

The Crown Vic is one of the most improved and researched vehicles. Chevy dropped the Caprice, but Ford kept the Crown going for many years. (1979-2011 Panther platform), and made many improvements.
The later Crowns were fast, bullet-proof, and comfortable.
One of the best cars ever made, as evidenced by the millions produced and loved by professionals.

Not really. The ones that are still on the road (millions) have a long way to go before they can think about resting.
