A lot of police departments went to those Dodge Chargers and now they are regretting it. They are junk. They are not near the cars the old Crown Vics. were.
They buy on fleet pricing. They buy a bunch of them and do it on bid pricing. Whoever has the lowest bid gets the deal. I worked at a dealer who did fleet stuff.
Local police department bough 140 Chevy Tahoe's about 12 years ago. They converted every one of them to CNG, for the tax incentives. They figured it up and with the tax incentives of using CNG vs gasoline, they'd pay for the fleet in 15 years. THe other side of the deal is that they struck a nice agreement with a company who oversaw the drilling for Natgas, so they were getting a HUGE discount on CNG (like close to free).
The tax incentives went away, the drilling companies left town (like they always do) and now they're STUCK with a bunch of CNG trucks that they can't sell and are too expensive to maintain.
So they did some car shopping and found that the Ford Explorer-GASOLINE-was cheaper to buy than the Tahoes. That and they're smaller, get better fuel mileage, more comfortable and have more torque to take off from a stop (this came right from a police officer's mouth).
Sheriff's office has a bunch of Chargers and the 3 deputies that I know personally don't care for them. I thought they were all V8's. Wrong, they're V6's which I thought was odd, but whatever. Again they buy them on bid so whoever's got them cheapest is who sells them., and then they're also in charge of warranty and accessory installation (at least here they are).
I'm back to dealer work and the dealer I work for also has powersports, motorcycles/atv/tractors/etc. Police department came in looking for 4 police bikes and we lost the bid on them-THANK GOODNESS. Let someone else have that nightmare-and that's exactly what it is especially if the dealer stays busy like we do.
The days of nice, low maintenance, diesels are gone forever. EPA has ruined them, and now they're so expensive that the only folk that want them is business owners who need a tax write off and then the younger generation who wants a great big expensive 4x4 with a diesel because they haven't grown up yet. Once they get the payments, though, they're starting to re-think it. I fell into it too, payments were $900/mo. Sold it within 3 months. Shopped trucks and found a nice used 2003 F250 4x4 crew cab lariat with 89,000 miles. 7.3L which I didn't want (wanted V10). But the money was right and the trade deal was right, my payments ended up at $118/mo for 19 months-which I paid off early, and kept the truck. Still have it, like it, but wish it was a gas burner.
