This.

You bought a very unique car that requires unique care. This is a sports car, not a Honda Civic.

On the flip side, research is key. Call around! Find the place that seems to know the most about the Crossfire, not just the cheapest. Once you find a place with a knowledgeable staff and good pricing, go for it!

The previous owner of my Crossfire paid ~$85 for the first oil change. I don't really find that too bad if the place knows Crossfires well. I'll pay more for peace of mind.
