German cars are notorious for expensive parts for one thing, it's not just the Crossfire.

Change your own oil! Get a little dirty and save some money.

I don't really care about a cabin air filter. I'll change it when my air vents quit blowing air.

Luxury cars including sports cars are expensive, that's why they aren't economy cars. Yes, the prices have dropped, but it was originally a luxury vehicle. Get used to it, or get a Hyundai Accent.

The dealers do suck, but I've had crappy Infiniti dealers too.
