Taylor Swift -- Didn't Smash Vintage Car ... It Was All An Illusion

Not even Taylor Swift is crazy enough to take a golf club to the gorgeous Shelby Cobra featured in her new music video for "Blank Space" ... one of the dudes in the video now says it was all just CGI.

Car lovers around the world were understandably aghast when they saw Taylor go full Elin Nordegren on one of the greatest cars in history (assuming car lovers watch Taylor Swift videos).

But Andrea Denver -- one of the male models in the video -- told our photog in NYC we can all rest easy ... Taylor's metal mutilation was as fake as her relationship with Jake Gyllenhaal.

Watch this video at your own peril … Andrea is better seen than heard.
