If he wont allow you to spend an hour on it then he cant be that bothered to sell it. It would run like sh*t and be so noisy that you wouldnt be able to hear any problems happening if there was any. Also you wouldnt know if the turbo was any good. Either buy it in trust or stay clear. If you do buy it all you can do is check it has a spark,compression test it and see if it turns over and you can hear the fuel pump. Maybe multimeter the batter to see if its nakered too
