I bought my SRT from Bonham as well. At the time (last July) it was the best deal for a new SRT. The Austin dealers were asking $31.7k ($14K off msrp), and Bonham gave me on for $29,000. I flew to Dallas, they had someone pick me up and drive me to the lot (over an hour away) and I drove it home (was at the dealer less than an hour).

They make their money through volume, they claim to be the largest Chrysler dealership in the world (sell over 600 a month). That being said, the dealership seems to consist of a giant dirt lot with a couple of trailers on it located in the middle of nowhere. The cars are all filthy (though they did have mine detailed for me, so it was clean when I arrived to pick it up). It had one small door ding and a tiny 1/2" scratch on the front air dam, but for the price I couldn't really complain.
