my friends father retired from NYPD earlier this year, preffered the crown vic to the caprice.
Just some thoughts
-The impala is a joke
-If a 6.8L v-10 can be stuffed in a crown vic I don't see how the 5.4 could really be a problem.
Other than that I actually agree with sandman on most of the stuff he presents, well the stuff I know about anyway
