* Engine size and type: A larger engine (like a V6) would have a higher top speed than a smaller four-cylinder.
* Transmission: An automatic transmission might have a slightly lower top speed than a manual.
* Axle ratio: Different axle ratios were available, impacting acceleration and top speed.
* Aerodynamics: Modifications that affect aerodynamics (like a camper shell) would affect top speed.
* Vehicle condition: A well-maintained vehicle will generally perform better than one that is not.
Keep in mind that these are estimates, and reaching the top speed will depend on various conditions, such as road grade, wind, and load.
