A jack is basically suicide tbh. Jackstands are fine, provided they're used correctly.

Ramps are nice, provided you don't need to take a wheel off, then you're using jackstands anyway, so, if you're buying one or the other, jackstands are a good option.

Personally, if you have the space for it, a trench is the best option, I had one previously and I miss it alot. Nothing leaves the ground, car just pulls in and is ready to go. Mine was like 2ft deep, so, maybe a little cramped, but very comfortable once you're in there working. You couldn't make a standable trench at home without engineering it anyway, so, a crawlable trench is really the way to go.

Another option, if you’ve got the ceiling height is a proper 4 post lift. Expensive, but you can justify it by doubling your car storage space.

IMO a trench mitigates the danger effectively.

Until you fall into it when you’re not paying attention!

Make sure it is shored correctly!

They're against the building code around here.

But fumes can collect in a trench, is that right?

Depends on the jack. The people I know that do this use a jack and jack stands rather than just a jack. The jack is just the tool to go up/down.

This should be drilled into the heads of anyone who touches a jack. It's only a tool for lifting the car onto jackstands.

Lazyness. I've been under a car dozens of times with them, never had an issue, but know it's not the best practice and try to use jackstands... but it's just so much quicker!
