Would you buy on a civic ('95) that had some rust on the rear quarter panels IF you wanted to eventually have a clean car?

How much does it usually cost to weld em on and do the body work? Not from a repair shop, but someone who does it on the side.....

Is this crap if you want a nice clean car? What about pretty clean? Should I avoid the whole process, even if the car is a GREAT deal?

I live in northeast Ohio so rust is a big problem, but I don't want a dirty rusty civic with shitty paint. I have enough money to spend to get a clean one... but this is a deal for a nice car
