Here's the other find that the 2009 street-view helped confirm.
I spotted this one at the start of the year but didn't post it because I wasn't totally convinced at the time.
The free-standing vehicle hoist was something that stood out as a match, but there are a few differences in the building features so I wasn't sure.
Also, there are literally hundreds of these corner auto repair shops in Sth LA, & most of them look quite similar.
To be honest, I thought we'd never find the right one.
When you switch to 2009 street-view, it shows some advertising banners around the top of the hoist that are dead-set giveaways.
