Posted this video on the Crossfire Facebook Page. One of the "fans" was kind enough to paraphrase what he's saying.

"They say they increased the engine volume from 3.2 to 3.5 liters and exchanged the cylinders. 19 Inch rims allaround, lowered suspension by 35mm and changed the brakes. Puts out only 300 hp though. He says its a good car, but its super enoying that the ESP does not shut off completly and if you reach its limit, it still understears and goes straight.... The cost of the whole package, including exhaust etc., is 28,000€, so about $36,000 which you could use to buy an SRT 6 and bring it to TVT to be honest"

There you go.
