What a weird review. "Low rent interior" and average interior space seems very contradictory to major reviews.
"The 2017 Soul has an impressive interior, with surfaces that are soft to the touch and a sturdy build quality. Materials are also upscale for this class. The Soul's cabin is spacious and there is excellent passenger and cargo room" - US News and World Reports
"Inside the Soul's cabin, everything still looks familiar and feels well-built with high-quality materials and soft-touch surfaces." -- Motor Trend
"As with other Soul models, the interior layout is ergonomically sound, and material quality is top-notch in the sub-$30,000 arena." -- Car and Driver
