I have owned the older 5k style QJ’s for probably 4 years or so now. I’ve done motors on them before, but they are certainly not tall enough to drop a motor out the bottom, if that’s what you want to do. I’m on the thiccer side and some cars can be a little tight to roll under on a creeper. Did some work on a Tuscon the other day and barely fit. But I have more room under my e30. Note that I don’t have those extended jack spacers things though, maybe I should get some.

I like them because they’re so low profile, they slip under the rockers of lowered cars very easily. They also allow you do driveshaft/exhaust/etc work unlike a mid rise life would.

All in all, I got mine for $600 used. Even if I paid $1200 I still think they would have been worth it. I do wish they went a little taller though.
