yes...I have had what I thought was just surface rust as well...ends up being a bondo ball. Spend the time making sure ahead of time its what you think it is. Also price parts you know the car needs currently and the "what if-s"..things that are likely to have probelms. Weigh the price option (including shipping for body panels)... A good tub/ rollin chassis is easy to find for a few thousand, but what you are looking at seems like a good price. FYI I have a chassis for sale for more than what you are lookin at but with a 993/GT2, heres a quick pic. Good luck..make sure and keep us posted on a new car if you get one!
