Looks like that bumper up front could take more than a 5 mph hit!
Compare how far it sticks out with the 1 on a ’76 chevette or ’74 vega.
Unlike today, i believe no power door mirror(s) avail in ’70s & older cars.

In reply to Big_Fun.

This looks like the notorious Golden Olive that was on the recent ’73 Grand LeMans and ’73 GTO (originally) again. At Buick, it was called Green Gold, but it is the same color with the same 46 paint code on the data plate.

FWIW, Olds called it Moss Green and Chevrolet called it Green Gold like Buick. There was no Cadillac equivalent. I always found it amusing the way GM used the same colors across the divisions, and just named them differently.

Be still my beating heart ! The last big block to be developed by any manufacturer . Add that this motor prepped equally against BBC, mopar 440 , Ford 460 and won the coveted big block shootout ran by Hot Rod magazine it just seems buick never got the love I thought they deserved . Yes stage 1 did but nothing beyond that.

Thank you Big_Fun. Yes, he did. He also owned a 1957 Packard Clipper, he bought used in 1959 and a 1964 Chevrolet Impala wagon with the 327cid.

No, you’re not wrong, just off by one cubic inch. If Grandpa had a Buick, than it was a 455. Same if he owned an Oldsmobile or Pontiac. The 454 was the displacement for the Chevrolet Big Block.
Your Grandpa had good taste…

I have a novice question. Did GM have 2 V-8’s? My grandpa had a 1971 Buick Electra 225 Limited. I thought it had a 454 cid. This Buick has a 455 cid. Am I wrong in the 454?

Can’t really go wrong with a convertible and a big block, can you? Would be a fun car to cruise around in. Need to get that AC and cruise working.
