It’s a question I can give several answers to, depending on what the asker means.  In physical terms, you could ride on it.  Here is a good example…in this photo of a worker and MSL, you can see the cruise shell is large enough to house a small couch with more than one person sitting on it.  The rover itself is quite large, I’d imagine good comparisons would be something on the order of a ride-on tractor-mower.
