my first porsche, is it worth it? Options

[440gordy]

I am about to buy this 914. it has a little rust but nothing i cant handle. Both the lower rocker tins are rusted out and there is a spot on the threshold where the rocker meets the door striker panel. Needs a battery tray and maybe bracket. some surface rust along the back trunk but should clean up easily. no rust in the front compartment. It is supposed to have a slipping clutch, probably oil soaked from a leak. all in all a really straight car. I did get it started for about 30 seconds by bypassing the fuel pump and using another pump and running fuel direct from a gas can and it sounded just fine. It appears to have 106k. if i purchase this i plan to tear it to the ground and repaint it completely. and make any needed repairs. I don't want to overpay for it and then be buried in it. From what i have stated can any of you give me a good starting purchase price and possible end value. any knowledge form you guys would be greatly appreciated!!
