Is it better to build, or buy a dune buggy? - free plan for buggy

I waited a Dune Buggy very similar to the following link.

However, my father, she says may be too expensive to build than it is, only to see the kit you buy. It would be cheaper? And plans are free, you can link to that particular error, it's better to build it.
