That would defeat the whole point of the analogy which is to compare to something familiar. Nobody is familiar with buying "custom cars" Custom houses is something that people are familiar with.

It might take twice as long. Software might cost 2000% more than expected and the end result might be nothing like what the buyer though they were going to get.
