I agree with walking away unless you plan to spend the next two years in major metal repair. Structural repair, floor pans, cowl area, rocker panels etc., take a good level of skill, time and money. Once that is done, then start on the interior, paint and convertible top. If you feel comfortable doing those things or have someone that can do the metal work for you and then you do the rest, maybe then it would be a good project to consider. For that car - "safe, reliable and nice looking" = big $$$.
