Welcome to the forum. Before I bought my crossfire I looked at many different "enthusiast" type cars and finally settled on the Challenger SRT/8. I love that car. However, i just could not pull the trigger on 40K+ for a new one. I saw a Crossfire while vacationing in Maine with my wife and we both decided right then and there we needed a roadster. Agreed, for the money, you simply cannot go wrong with a xfire.
Yes, premium, the stuff that's 4 bucks a gallon right now and soon to hit 5.
These cars are real easy to change the oil, save some sheckels and do it yourself. Keep your eyes peeled for sales and you can buy the oil for around 4 bucks or so a quart. Advance Auto has the filters everyday price for around 11 bucks.
