You probably have already done an estimate of what it will cost to restore the Kar to where you are happy with it. Go thru that again and make sure you haven't forgotten anything. Add that to the $30,000, if that's the price you have to pay. My guess is that is going to be at least $50,000?
What is a similar Kar worth already restored to a similar quality? Probably not more than $50,000? So, is this a good buy? I would say only if this is the Kar you really want... right model, color, interior, options. If that all adds up then buy it. One thing is that K codes have been steadily going up and should follow the path of Shelby Mustangs, to some extent at least. So you're in it $50,000, that's a lot of money but in a couple of years it hopefully will seem like a good deal.
The argument that the drive-train is worth $10,000 alone is true but not relevant. You're not going to pull the drive-train out and use or sell it separately, makes no sense. And if you did, the rest of the car certainly isn't worth $20,000 because a number of Kars missing the original drive-train have been up for sale for somewhat less.
My estimate of $15-20,000 is figuring that restoration would cost at least $25,000 (just a guess since I haven't seen the Kar, plus the fact that it always costs a lot more than the estimate) and I think a similar Kar (restored) could be bought for less than $50,000 and a person just might find one they liked better (if they wanted a different model, color, options, etc.
There is always the fear that you're letting a great deal get away. But at $30,000 I would say this is no screaming good deal, at least not right now... it well might look like it in a couple of years.
Good luck, I'm anxious to know what you decide!! <img src=images/icon_smile_big.gif border=0 align=middle>
