Sealey 1050CX
Price: £20.98 Minimum saddle height: 110mm
How low can you go? Ground-hugging minimum height sets this jack apart. This super-low figure does not detract from max lift, either, at a reasonable 351mm.
The saddle seems small, though, and the lugs are not as pronounced as we'd like. Rather short lever would make lifting heavy cars hard work, too.
