What’s the most surprising sleeper build you’ve seen or built?

There’s nothing sweeter than watching a beat-up-looking Volvo or an old wagon absolutely demolish some high-dollar exotics. I’ve been obsessed with sleeper builds lately especially stuff that flies under the radar until the light turns green.

One of my favorites was a buddy’s LS-swapped Chevy Malibu wagon. Looked totally stock down to the hubcaps, but it had a built 6.0 under the hood. The thing was an absolute monster and caught so many people off guard.

What’s your favorite sleeper build? Could be something you’ve seen, driven, or even built yourself. Bonus points if there’s a good story behind it!
