Longest Production Runs Without Major Changes

Last time I looked, they still make the Mk2 Jetta and the XJ Cherokee in China.

If we are going to go beyond cars. I will throw my boat into the mix. The GP14 was first designed and built in 1949. The design is still going strong and new ones are being built every year. Originally made of mahogany and mahogany ply, they are availible in 'glass or wood new today. Over 16,000 built and still going.

Panther platform LTD/Crown Victoria.

1979

1991

The Nissan D-21 truck was built from 1986 to 2008, although not available in this country after 1997.   

Crown Victoria again...

1992

2011. The last one ever, right here:

I loved the panthers. I drove a 79 from 86 to 2000. Also had a 93 and a 95 p71.

I feel like I should find a clean 2011.

Does the 911 count? It's grown like 8 inches wider and 10 longer since 1963. Some horsepower and aspiration changes, but still the same basic beetle look.

In reply to RevRico :

You can't put any parts from a Carrera on  '64, though.

Porsche 928, 1977-1995

Chevy Astro 1985-2005. Only 2 generations '85-'94 & 95-'05. Parts ALMOST fit both generations.

Love my '93!

Jeep CJ's.    You could say from '41 to the first Wrangler.  I forget the year.

Jeep J-series full size trucks. 1964-ish to 1991.

Funny part is, they were designed by Brooks Stevens, one of the people who helped sell the automakers on the principle of planned obsolecense.

Planned obsolescence only works if the parent company has enough money to fund a restyling.

Related, Channel Lock Pliers from 1934:

22 short:  1857 - still in production.

(by definition it has to be almost exactly the same)

(if you want to be a bit more broad... get it... broad):

64,000 years:

Well, if we're going to stretch it that far, 4.543 billion years and it still in production. 

The Toyota Tundra almost matches the Frontier in terms of time since last chassis refresh. With the way things are looking, the may be able equal. Sounds like Nissan is about ready to axe the D40, and the Tundra isn't slated for replacement until 2020. 

Mercator K55K.  1867 - present. No changes.
