HPOF Requirements... What are they?

Recommended Posts

I am new to this portion of the AACA forum and to displaying and showing cars at an AACA event. If this info is somewhere on the website I missed it. Sorry.


Re: 1970 Mark III, 47,000 mile un-restored car. I would like to show or display it at an AACA event. What are the HPOF requirements.

Re: Second Generation Cars: What are the Requirements for show or display?

Thanks for your Help Guys!

From the judging guidelines:




Since its’ founding, AACA has been dedicated

to the preservation,




of vehicles. In the furtherance

of the “preservation”



AACA Board of Directors in 1987 established

a program to encourage

the saving

and display of collector vehicles in

their original,



The Historical Preservation

of Original

Features program


owners of

vehicles 35 years old and older, retaining


original features to allow them

to remain in this original condition, and to

show them at National Meets. A vehicle

may be entirely


or it may have

certain “original” features such as paint,

chassis, upholstery,

engine compartment,

etc., that are essentially as delivered.

These vehicles will not be point judged.

They will be certified using a percentage

system which includes a total average

percentage of the original features of the

exterior, interior, chassis and engine. The

vehicle must receive a score of sixty-five

percent (65%) or above to receive certification.

They will be recognized

at the awards

ceremony and will receive an exhibition

award (and a mounting board at first certification).

A certification

badge will be presented

to each vehicle upon acceptance

into the HPOF category. The badge should

be mounted at some visable location on

the front of the vehicle. Vehicles


the HPOF category will be prohibited from



in any other competition

or exhibition

class. If the vehicle is

restored, certification

in HPOF category

will be voided.

No previous National First

Prize winners are accepted. An HPOF certified

vehicle that is significantly restored

will lose its’ HPOF certification. HPOF

certification remains with the vehicle even

if there is a change of ownership. (See

Attachment 5 HPOF Judging Form p. 48)



This display class is for factory-assembeld

manufactured vehicles that replicate the

look and style of a previous make and

model. Vehicles must be 25 years of age

or older to qualify. These vehicles have a

newer, more modern driveline and chassis

than the original vehicle on which the

replication is based. The body may have

fiberglass components and the interior may

have modern accessories. A special team

appointed by the VP-Class Judging will

evaluate this class. The evaluation will consist

of inspecting all areas of the vehicle with

consideration for workmanship, condition

and being factory built. After acceptance

by the evaluation team, the vehicle will

be certified SGCV. After certification, the

vehicle owner will receive a SGCV badge at

the awards banquet to be displayed on the

front of the vehicle. The vehicle owner will

also receive a participation "chip" from that

meet. After four more participation "chips"

have been received, the owner is entitled

to a special SGCV "plaque board" to place

the participation chips on. Vehicles will be

accepted into this class after providing evidence

of being factory assembled by either

a copy of the manufacturer's Certificate

of Origin (C of O) verifying it being a factory

built vehicle or the manufacturer's

"build sheet" or "production order" with the

vehicle's serial number and production date

documented along with a photo copy of the

vehicle registration or title. Factory contact

information, names and phone numbers

should be included with the application, if

available. All applications must be accompanied

by a "C of O" copy or build sheet

information along with all other pertinent

documentation and sent to the VP-Class

Judging. Vehicle acceptance is on a caseby-

case basis and at the sole discretion

of the VP-Class Judging with approval

from the Class Judging Committee. Meet

registration will not be accepted for these

vehicles until the Vice President - Class

Judging has reviewed all the documentation

and approved it for entry. Vehicle

owners will be notified of the decision. The

AACA does not accept "kit car "

vehicles. Included in this class are factory

built: Avanti II, Clenet, Glenn Pray,

Shay & Zimmer. Other vehicles may apply

to the VP-Class Judging. (see Attachment

7-SGCV Judging Form-p. 50).

Hey Mathew,

Thanks for your detailed reply. I do appreciate your time.

Can I ask another question Re: HPOF Requirements...

The bottom side (suspension and frame) of my car received little or no paint from the factory when built so it has a lot of surface rust. If I clean and respray the components black to stop or prevent anymore deterioration does that detract from the cars certifcation scoring?

Thanks again,

Mark Tyra

Mark, the other option would be to gently clean things and spray it with clear. What dirt gets trapped under the paint would help to show it hasn't been restored/atemptmade to do so, and is orginal but just cleaned up and an attempt was made to preserve it. The cleaning and spraying black would fall more as restoration.

As for the 65% in order to get certified, that is the avearage of the % score for each of the scroing catagroies; Interior, Exterior, engine, chassis.

My understanding of the class is that it was formed to do a couple of things.

First, it gives owners of unrestored/minorly restored vehicles a class of their own so that they can show their vehicles on a level playing field and allow spectators to see and enjoy these survivors.

Second, it helps other hobbiests because they can use them as a correct visual reference when they are restoring their vehicle, which may have been altered before they got it, or have parts missing and they have no idea what they need to be looking for until they can see an orginal part.

Hence the name, Historical Preservation of Original Features AKA HPOF. :)

My 69 442 also has similar surface rust and or minor oil seepage on the underside. In my opinion if yours has survived since 1970 with the surface rust LEAVE IT ALONE. If you tell me it's in a wet barn or swamp based garage then you might have no choice.

I looked at my car many times considering a re-paint. I'm so glad I left it alone!

They are only original once!!

Would a repainted engine or re-chromed bumpers and moldings be a no no?

Both would be deductions, but those items alone would not prevent it from being considered for an HPOF Certification.  Please note that this is a 12 year old post from 2009 and that the evaluation criteria for HPOF was significantly revised in 2013.  There is no 65% rule anymore, it is a point deduction system.  You can download the current Judges Guidelines from the AACA Home page, which contains copies of the current HPOF and HPOF Original judging forms.
