Joking or serious? The smaller body Olds 88 (like your avatar) and the smaller body Buick Special share the same body proportion/lines. You've got a 53 Olds 88, cool car BTW. I've got a 53 Buick Special. We should be able to figure this out. The posted car has obviously been customized. Cadillac dagmar bumpers, chopped, lowered, frenched headlights, scoops in hood sides, scoops in upper rear quarter. Other than the Olds wheelcovers, everything else says '53 Buick, no? Buick hood, front fenders, headlights, side trim, rocker trim, hood ornament... Even the area between the dagmars appears to be modified sections of both the upper and lower front bumper of a '53 Buick. From the cowl back, the Buick and Olds are essentially the same. I just can't see some one taking an Olds and changing everything over to make it appear as a Buick. Wouldn't a person just start with a Buick to build this car?
Though one of my favorites, that is a 1961 Buick that's owned by Bob Owens of Owens Salvage, not an Olds
