Freedomlou,
While I do agree with small parts of your post. I would not say they are not designed for youth, there are plenty of young people on crownvic.net sure they buy the cars used but they still buy them and WANTED to buy them. I bought my 2003 Crown Victoria at age 25, Yes it was used, but thats not what I wanted. I had a black 2004 Mercury Grand Marquis LS Ultimate with the HPP package picked out and contract signed unfortunately I was so buried in my previous vehicle I couldn't afford the payments. I am a big guy, 6'3" and I like a big car.
There are two major reasons why the Crown Vic/Grand Marquis went stale.
1st. Zero advertising by Ford Motor company, which translates into no sales therefore no redesign. They were much to concerned with buying Volvo,Land Rover,Aston Martin and Jaguar to care about the Panthers
2nd. All of the Ford dealerships who would only order the Crown Vics that Ford forced on them and then buried them in the back corner of their lots behind 8 rows of F150's and Explorers. A little advertising can make or break a vehicle.
All in all, Yes a major redesign would breathe a lot of life into this somewhat outdated chassis , but had all of Ford, Including the dealers themselves not forgotten about the cars things may be different.
