remember that parallelism is really of 2 types: GRAMMATICAL and LOGICAL.
in your case, v1 though v5 all happen to be in the same tense - present tense, because we're talking about unchanging features of minivans - but ONLY v2 through v5 are LOGICALLY parallel.
v1 describes the van's passenger seating capacity, which is NOT presented as a point of superiority over sport utility vehicles, while v2 through v5 specifically describe advantages of minivans over sport utility vehicles.
therefore, the sentence is written with v2 through v5 in list form, but, because v1 isn't in the same category as those others, it's (rightfully) excluded from that list.
