Hi Dane,
Humble Opinion:
1. Depending on what you have time to do, & how you want to do it, maybe first see if it runs -- the engine & mechanical components may be great.
2. Second, if you would like, go on line & Google for example: "1930 Model A Ford sedan for sale", whereby one can see what is being offered "today", & review current Model A town sedan prices -- prices vary a lot.
3. One may be surprised to see what this car would look like, & moreso the effect on selling this vehicle if this car were carefully washed & waxed with the right professional products along with interior cleaning -- used car salesmen are fuly aware of this difference as opposed to selling "as is".
3. Not very expensive to clean up & touch up engine compartment -- maybe go more original with Model A head, new hoses & vintage period hose clamps, etc., etc. -- up to you.
4. Asking price? For some who are used to buying cars at today's prices, $5,000.00 up or down may be peanuts for some, a fortune for others -- all depends on "who" is interested.
5. If the asking price is considered a bit high by some, it can be negotiated & lowered -- if low, difficult to raise the price unless two rare buyers are trying to out bid each other.
6. In looking at similar town sedan vehicles, wood bodies can rot easily if stored outdoors in a humid climate; hence, if the wood body is good & interior good, please be aware that both are extremely expensive to replace; however, if both need replacement, material cost alone is about $1,800.00 for a wood kit, & about $2,500.00 for an interior kit, or $4,300.00 in materials alone -- labor depends on if you do it or a professional does it -- so if you see a town sedan that needs new wood & a new interior, a knowledgeable Model A buyer person wil not offer much for it.
Sincerely hope this helps.
