I bought my 03 Black from Bernie Katz (BJ Motors) on April 17, 2010. In 22 months, I've put about 4500 miles on it, and I smile EVERY time I drive it. It had 22,900 when I bought it, and came slightly modded - ECU, exhaust, plugs/wires, K&N, MGW shifter, Aldan-lowered. Since I've owned it, put PS2s on it, and had the oil cooler lines replaced last year as they were seeping (common issue on the 8.3, especially in the SRT Rams). Other than that, changed a few fluids, and I drive! Knock wood (don't want to jinx myself), but it's been a good car so far. May need brakes at PA inspection time in May, but that's to be expected. I am the 3rd owner. Before I bought, Bernie checked out it''s history, and made sure all recalls, etc had be done. I also had my local dealer run the VIN to check it out as well.
Bernie Katz is well known on this forum for selling cars that work; in essence, he is doing the pre-purchase inspection for you! Recommend you contact him.
Every once in a while, I get the "bug" for a Gen IV, but it would require me parting with this car, AND my 07 Superbee SRT, which I'm not willing to do. The Gen III already has more power than I can use. I regularly go on drives with the F-car and P-car guys from my C&C , and never have any issues with wanting more! Lots of good cars out there.
