Hi there, and welcome to the forum!

Maintenance costs depend on how much maintenance you are comfortable doing yourself. If you can handle doing your own oil changes, that will help quite a bit as they are the most common maintenance. The oil changes on Crossfires are quite easy. The oil filter is accessible from the top of the engine unlike most other cars. There is a skid plate that needs to be removed from the bottom of the car to drain the oil, but that is just 5 bolts. If you have ramps, that eliminates the need to jack the front of the car up.

The biggest cost with an oil change is the price of the oil itself. Synthetic Mobil 0w-40 is recommended, and it costs anywhere from $5 to $8 per quart, and the engine needs 8 quarts. The good German-made fleece filters cost about $15 each. So just in oil change consumables you are looking at $80 plus. Most dealers will charge well over $100 for the oil change assuming they are using the correct oil. If they quote a cheaper price, they probably aren't using synthetic oil.

You should be able to find a clean SRT-6 coupe with under 50k miles for $15k. The lower the miles, the higher the price. Be prepared to travel nationwide for the best deals and cleanest, low-mileage cars. I drove 9 hours to buy my roadster in February.
