This is a quick little walkthrough for help on how to beat each challenge.

3.1 Rock Crawler

Start off going forward. Go to the left of the checkpoint to climb up the rocks even easier. Now when you get to the top, turn right. Go to the checkpoint and then slowly go down the hill in front of you. If you go too fast, chances are you will flip over and fail the challenge. Now just go to that checkpoint that you should be looking at and then start going to the next after you touched that one. Climb the cliff early so it won't be so hard to climb it later and then just drive into the checkpoint.

3.2 - Snowmobile

This one is a very hard one and you will probably just beat it by a few seconds. Just take your time. Speed up on straight aways and slow down a lot on turns. If you don't slow down a lot, you will spin way out and will probably make you fail the mission. Just stay on the road and keep doing that.

3.3 - Swamp Buggy

This one is hard and they just give you barely enough time. What you have to do is go forward and into the water. Pull out the swamp buggy equipment right before you enter the water so you will lose very little speed. Just go into all of the green arrows and don't touch the red arrows. If you do this correctly you will have about three seconds left in the whole mission. Just get out your wheels at the last checkpoint and finish the level off.

3.4 - Wheelie Ambulance

This one is easy. Just do a wheelie be pressing the special button and keep doing it right when you start the mission. You have to accelerate to do it too. Just slow down and stop if you don't do a wheelie and then accelerate again. When you reach the requirements to finish the mission, just drive down to the end.

3.5 - Limo Fire Truck

This one is easy except you just have to make a really quick approach. You have to drive up to that line as quick as possible and pull out the fire hose. Just turn it on and point it towards the fire. If you did it quick enough, you can go do something for the next few minutes. Just wait there and you should eventually finish the level.

3.6 - Switchblade

Just go as fast as you can or take your time. You should be able to finish this whole challenge easily.

3.7 - Golf Ball Collector

Same as the switchblade challenge. Either go fast or take your time. It doesn't really matter as long as you get it all done as fast as you can.

Alright, let's talk about some quick tips and tricks for Underground Garage that'll shave some time off your projects. You might already know some of these, but they really do help speed things up, even if it's just by a few minutes here and there. We'll go from the basics to some neat little shortcuts.

First off, the basics of working with screws: to unscrew them, you'll want to hold down the right-click button. Conversely, to screw them in, you'll hold down the left-click. If you're left-handed, it might be the other way around, but I'm not entirely sure on that.

When it comes to cutting and welding, the key is patience. You need to slowly move your tool across the line. If you rush it, you'll likely mess up and have to do it all over again, so take your time here.

Here's a handy one for when you're using the jack: as soon as you start lifting the car, you can immediately begin unscrewing the tires. You don't need to wait for the car to be fully raised off the ground.

My biggest advice? Always start by buying exactly what you need. Getting the right parts upfront will seriously help you finish your projects faster.

And for installing parts, there's a quicker way than dragging and dropping. You can actually install parts faster by just clicking them in your inventory. It's way more efficient!
