Very few mid-sized vehicles have the width to accomodate a 48-47.5" wide sheet of anything. I use a utility trailer for this kind of thing and have for a decade and a half.
Or get it delivered
Or rent one of Home Depot's or Lowes' "$19.99 local use 45 minute" trucks. It helps that Lowes is 1/2 a mile away (1.2 miles back, as odd as that sounds), and Home Depot is only 4 miles farther away.
Oh, I've also rented a $19.99 U-Haul, such as when I seriously overbuilt my workshop. I mean, I live on Long Island, but I still wanted a roof capable of a 3 foot snow load, sidewalls I could stand up next to, and needed to keep the roof under 8' for code reasons (it's 7'11 5/8").
After my original drawing, I shortened it by a foot (and took out the mid trim) and heightened the walls a half foot from my original plan (which then required me to beef up the roof without adding a lot of roof load by doing so).
ANYWAYS: because I overbuild (it's all I know how to do), it weighs 3 tons, meaning, the stuff was too heavy for my then-Outback, and even now, for my current Ascent.
And for $20, I'd rather not be dragging big lumber around in my interior.
