We’ve all seen the car driving down the street with a garbage bag duct taped over a broken window. As dangerous (and hilarious) as that may be, it is by no means the limit of amateur automotive engineering ingenuity. These pictures, from the always-hilarious thereifixedit.com, show just how creative people can be when it comes to making changes to their vehicles. From the hilariously haphazard to the creatively upcycled, these insane vehicle mods are perfect examples of do-it-yourself gone wild.

When you’re moving and you just can’t spare the $29.95 for a U-Haul, what can you do? Maybe…shove way more into the car than the car can possibly handle, and then duct tape a bunch of boxes onto the top? Yep, that sounds good.

For many car buyers, choosing between a sedan and a pickup can be a difficult decision. But this car owner decided to take matters into his own hands by combining a Volvo, a pickup bed, and some mad woodworking skills. Note the nice, even, sturdy-looking construction.

This truck owner, however, doesn’t seem to have the same level of car mod talent. This wooden truck bed leaves so many questions unanswered: where did the truck’s real bed go? Who thought constructing a new one out of wood was a good idea? Is it supposed to be an environmental statement? Is that even street legal?

When you really, really love your car, it can be hard to admit that it’s at the end of its life. But when it’s held together with trash bags, duct tape, bungee cords and what appears to a flannel shirt, it might be time to let it go to that great parking lot in the sky.

Apparently the load was a little heavy on the back end of this van, and maybe the bumper started scraping the pavement. Rather than, say, fix whatever is wrong with the frame that’s making the back end sag, this resourceful car owner decided to put some teeny-tiny wheels under the bumper. Problem solved!

Spare tires are expensive. But with some ingenuity and a few of the odds and ends that everyone has lying around their garage, there’s no obstacle that can’t be overcome. Hopefully the guy riding in the back of the hatchback is wearing his bungee-cord seat belt.

We may kid about these modifications and temporary solutions, but some of them actually serve a purpose, albeit a funny one. This shopping cart bike was concocted by Ryan McFarland and can solve the irritating problem of where to put your groceries when you go to the supermarket on your bike. If you’re itching to make one yourself, there are instructions here.

If you’ve got access to the equipment necessary to weld a whole new side panel onto your minivan, why not? It’s cheaper than buying a new van, and it’s not like it’s completely unsafe or anything, right?

Appliance delivery, like spare tires, is not cheap. You can accomplish basically the same thing with a car, a dolly, and a friend or two willing to ride in the trunk all the way home.

Who said you can’t put a trailer hitch on the inside of a hatchback? This insightful car owner knows that you can haul anything if you just put your mind to it.

At first this looked like a wood-burning stove in the back of a van. But on closer inspection, it appears to be some sort of creative vehicle recycling. We don’t know what it’s supposed to be, but kudos to the creator for using existing materials that might have otherwise gone to the junkyard.

Motorcycle seats can be very uncomfortable. So what’s a biker with a bad back to do? This looks like a pretty great compromise between car and motorcycle.

Motorcycles have another small problem for those who enjoy hauling things: very little storage space. There are, of course, trailers made just for motorcycles, but where’s the fun in that? This crazy modification turns the motorcycle into a tricycle, and the car hood into the awesomest trailer ever.
