2 post lifts are pretty cheap. You might look into that. The only problem is unloading one on delivery. But there are ways around that and you can get them installed for extra $$.

I imagine the oil changers each have a vendor who fabs the stair, angle iron frame at slab opening (with embeds) and the guide rails. The owner would typically furnish those types of items to the GC and the GC/Subs would install.

I'd personally go with a lift as they are pretty inexpensive ($3-4K) and allow you to park two cars in the space of one when not in use.

I agree. Easier to get a home permit for one of those as opposed to the "grease pit" alternative. Just don't let the home owners association know about it! They tend to frown on anything indicating the potential for shop tinkering....

You forgot that.
