One should be able to get a very low mileage SRT-6 Roadster for no more than $30k. Check Ebay, there are several listed. I got mine for $29.5K a couple of weeks ago with only 4,441 miles. Another just sold via buy it now on Ebay for $29,750 with just 2,700 miles.

I would offer them $30k for it if it has low miles.

Good luck.
