Although the 2010 Nissan Cube remains largely unchanged from the 2009 model year, Nissan has added another trim level, the Krom (rhymes with “home,” not “prom”). The Krom adds a healthy $6,450 to the base model and is nearly $3,000 more than the previously highest trim level. What do you get for all this extra money? And does any of it justify a Cube costing over $20,000? Cars.com senior editor Joe Wiesenfelder gives his take in this review.
