Wow theres some rust on that poor car. Well for 150 its a GREAT GREAT DEAL!!! First off theres obviously been water damage. I had to do the same thing , just not as bad.

1)uunbolt the seats and remove the carpet, This will tell you if theres any rust thtough on the inside. If there is then have a body shop weld steel shet metall over it, then spray it with some rustoleom, my favorite redneck place to go for welding here and there is Maxi muffler. If you give then the sheet metal they often will knock out the rust and weld it for about 35 dollars per 1/2 sq foot. You may want to have a body shop do the ones under the hood. It may be and extra 300 but it makes things easier! :)), was your panels with mild soap and water.

2. have a fender put on and paint the whole stinking car while you have it apart do it looks good and doesnt rust agian! I was charged 1500 at a Local Certified First Shop " only uses OEM parts" Mine is just being finished this weekend.

You may have 2000-2500 it it before the body is right and its painted but you will feel like its worth it! Ofcourse there are budjet paint shops too but I would go with quality!
