Our ' 47 Ford cost us a bit over NZ$25,000 (about US$20,000,) about fifteen years ago.
Motor and box (350 Oldsmobile,) was under the bench, Jaguar suspension came from a wrecker for around $800, panel beating around $2000, most expensive item was painting at around $10,000, and the car itself cost $4,500.
(All NZ$.)

The rest was upholstery and incidentals.

And it could have been less if I wasn't so lazy and farmed a lot of the work out!

(Nah...at that stage of life I was working all hours I could...)
