Jeff, I am not a mechanic, but I have owned several airplanes and I will share something with you that others have tried to tell you. There are NO BARGAINS in aviation, no steals, no hidden gems for first time buyers.
Trying to buy a complex retractable on a shoestring budget is going to either ruin you financially or at least get you out of aviation.
Have you ever seen the movie, "The Money Pit"? if not rent it, subsitute a bargain airplane for the house, use the same basic story line.
The aviation market adjusts to value, there is a reason a Baron sells for more than a 310, or a King Air brings more than an MU2, value.
I am not bashing the Viking, but you're expectation of putting a couple grand in a bird that hasn't flown in many years is far from realistic. Hoses, belts, mouse poop, prop overhaul or at least reseal, no telling what the ancient avionics are going to do after a couple uses.
You could easily spend $10-20K on an airplane like this and still have a $20K airplane.
But, that is just friendly advice from a guy trying to help you.
Please notice, that not one person here said to hurry and grab it before someone else beats you to it.
We'll I have to say that if I had more money I would indeed purchase something different. The Viking seems a remarkable value for the money-- if and only if it checks out. If I could keep the price tag under $30k and have an airworthy cross country machine I will be happy. I already have a hanger so it will be out with old and in with the new. I've never owned a complex so I'm figuring on 50% more expensive maint cost than I pay on my current tricycle. And insurance is not a problem. If I can hit the numbers right I'll be happy. Looking over the logs it appears that quite a bit of money was put in The airplane from 2002-2006 I'm excite for now. If it doesn't check out than ill walk and keep looking. I have to say that people told me I was cray to buy an old worn out cherokee as a student pilot and that bird has been amazing I could walk away from it now and get nothing for it and be money ahead of renting so I'm cautiously optimistic about an old complex bird, but we shall see
