Am cobra for sale

[big block]

Hi guys I am looking at a couple of cobras for sale and was wondering if anybody knew the previous owners.One is with sovereign it is a 2011 Ak with A 350 Chevy quote's near 400 bhp? I am not totally genned up on Chevy's but understand that they start at about 200bhp so without driving it how would you know. The other is at Hallmark and is a 2011 Dax with a ls3 engine with dyno printout.I would appreciate any comments on the cars and the companies if anybody has had dealings with them, cheers.
