Remember where that car was built...according to a 1951 model year distance/cost chart, Kaiser-Frazer charged $252.17 for freight from Willow Run to San Francisco. No Henry J's were assembled at Long Beach or Portland.
Confidential Bulletin #56 dated 1/26/51 indicates group #22 was offered only through February 1, 1951 (production...cars could have been in inventory for some time after the production cut date). It shows a price of $180.95 plus 9.31 Federal Excise Tax. At this point, the base price on a HJ deluxe (K514) was still $1,342.58 plus $71.42 Federal Excise Tax and $15.00 suggested for prep and conditioning at retail delivery. Overdrive was at the time $91.00 plus $5.01 Federal Excise Tax. These figures on the car and o/d come from Confidential Bulletin #52. So Far, what I have listed here comes to $1,966.44.
At this point, we are still $133.56 short. If the car was sold retail after March 1, 1951, regardless of production date, OPA price control regulations would have allowed dealers to charge $1,378.29 plus $105.61 Federal Tax and $98.15 (including Federal Tax) for o/d.
Further, even though factory MSRP on the cars did not include Retail Delivery Report (RDR) Deposit ($5.00) Factory Service Charge ($10.00) and Advertising Charge ($20.00) the costs were passed on to customers by most dealers. I would guess the balance is a mixture of state and/or local taxes, license and title fees, whitewall tires, etc. The little things quickly add up.
