Any ideas on what this might go for if the underside is clean?
It looks like that car has power windows, so I would hope they all work and I can not tell whether it has a/c or not but I believe from what I see underhood and inside that it does not. In any case, I see this car as likely between a condition 3 or 4 using the attached buyers guide, that is about the best I can do these days to estimate a vehicles value from the 50s, and now is not the best time to be selling anything (this site has, over time, been the most reliable predictor of value for me). If the engine runs well and the trans shifts as it should, the brakes feel good and the options work pretty well and there is minimal rust on the car, the price could vary from as low as $4K up to about $9K would be my best guess for a sedan, but maybe even higher if the car really impresses upon inspection............:

Condition Guidelines
These are condition guidelines to help assess a vehicle's condition. Keep in mind that there are many factors that affect value. For example, a "barn find" may on the surface look like a #4 or #5 vehicle, but it's time capsule character often means it is worth far more than it's condition would normally warrant.
#1 Excellent: A close to perfect original or a very well restored vehicle. Generally a body-off restoration, but a well done body-on restoration that has been extensively detailed may qualify. The vehicle is stunning to look at and any flaws are trivial and not readily apparent. Everything works as new. All equipment is original, NOS, or excellent quality reproductions. Note: cost no object concours restorations should be considered 1+ condition.
#2 Very Good: An extremely presentable vehicle showing minimal wear, or a well restored vehicle. Runs and drives smooth and tight. Needs no mechanical or cosmetic work. All areas (chassis not required) have been fully detailed. Beautiful to look at but clearly below a #1 vehicle.
#3 Good: Presentable inside and out with some signs of wear. Not detailed but very clean. Body should be straight and solid with no apparent rust and absolutely no rust-through anywhere. Shiny, attractive paint but may have evidence of minor fading or checking or other imperfections. Runs and drives well. May need some minor mechanical or cosmetic work but is fully usable and enjoyable as is.
#4 Fair: runs and drives OK but needs work throughout the vehicle. Body shows signs of wear or previous restoration work. Any rust should be minimal and not in any structural areas. Cosmetics, body, and mechanics all need work to some degree.
#5 Poor: In need of complete restoration, but is complete and not a rust bucket beyond repair. May or may not run. Not roadworthy.
Parts or Salvage: Incomplete vehicle most useful for parts. Generally, take 50-60% of the #5 value
