Thorough vehicle inspection and repair call for the ease of access to the bottom assembly. It would be too difficult to do if mechanics had to work in a cramped space with just a few inches of clearance from the ground. Increasing the clearance should be the first thing on the agenda.
A portable auto lift works best for this task. It can be thought off as a much larger jack that is capable of carrying the whole weight of the car in a balanced manner. Only a small part of the underside is covered by the lifting mechanism. Important components are exposed for inspections.
Unlike other types of lifts, this one is not bolted to the ground. They are meant to be relatively light and portable with small wheels and a handle. Moving it around the repair shop is easy.
