I looked at the ad, boat looked good to me but keep in mind, I am used to salt water boats that look like crap after 5 years, so that one looks great! The Cobra is the joint venture drive so it's the same as a Volvo SX. The only other thing I'd be concerned about, is if parts are available for the fuel injected Ford engine (fuel injection and ignition parts). I'd look over at
http://www.dougrussell.com and check in the OMC parts section, to make sure you can get those parts. Volvo did not use Ford engines for a long time, so that may be an issue. Again, you need a pro to look at it. We can't really tell you much, other than it looks good for the age. One other thing, is that it really hasn't been used much in all those years. I hope it was stored and winterized properly.
