I've had my 01 sport for 4 years and have put roughly 60k HARD miles on it (I make sure my trac-loc still locks up every chance i get, and have changed my rear tires 9 times haha) Its now at 120k, torn down in the process of being painted satin black. besides the normal issues of coils, replacing the coolant tank, and pcv pipe (that one was a bee eye itch) its been good to me, especially considering how abusive I am. Luckily i can do all the work on it myself, and get all my parts at wholesale, so i guess that helps the frustration.
If your issue is the coils, and you can get around under the hood, I would highly suggest dropping the 50 bucks on a basic code reader. It's usually a single coil that causes the headache ($45 at auto zone) and if you've recently changed your spark plugs, you don't really need to again, just see which cylinder is at fault and pop a coil in it.
By the mileage an age of your car, your problems sound excessive, I would trace the cars roots and make sure its not what we in the dealership industry have dubbed "a katrina car" they're out their, they went for a swim 5 years ago in New Orleans, and they're nightmares!
