- Sub-compact
- A passenger car containing less than 109 cubic feet of interior passenger and luggage volume. A designation no longer used because even full-size cars are now about the size of what was the compact car. In 1970, for instance, a Chevrolet Impala was a full-size car, a Chevelle was an intermediate, a Nova was a compact. When cars smaller than the Nova came out (i.e., Chevette), they were called sub-compacts.
- Sub frame
- A partial Frame that is sometimes bolted to the
Chassis of unit-body cars. It can be used to support the engine,
Transmission and
Suspension instead of having these
Components directly connected to the main body
structure. This more expensive design generally results in better road isolation and less
harshness.

Any negotiated change in the terms will result in a different net interest rate.
