My 73' duster PROJECT

Wow, now that I look at the car for 1500$ he should have included the cragars. This car is pretty bad, I really don't know if I am up for this big of a project. Somehow water had been leaking in and the insulation under the rubber floors got wet. The passengers side floor is gone, almost totally. Drivers side has no holes to my knowledge but has such heavy rust that it would need to be replaced, and the other day after it rained there was actually a puddle on the drivers side floor.
This has really got my hopes/ambition down. I don't really know if I want to get involved with this car. I really wish my dad could have looked around before purchasing this particular duster.
