If you mean the 2104 and 2105 scopes, I would not consider them suitable for automotive use for many reasons.
You would only be able to use these on a very few automotive signals and in a very limited way..
If you are interested in automotive scope application I would get one of the automotive kit packages. They are the best value and you will have virtually no limits on what you can do with automotive scope analysis.
