About Rowhouses with Mechanics Garage
Oxum's is great but they don't do the sort of work a modern modular car needs. This garage, set in a row of houses, has working ramp and lights - you'll need fuel for the generator, but I assume you didn't push that jalopy here...?
This monument has three interior rooms, the garage, a fuel exchange room and a water room upstairs.
