Compare the positives and negatives with points. Like cx7 is cheaper than the RDX (similiarly equipped by x dollars). Then decided a value that the money difference is worth to you. Id suggest a +1 for every thousand bucks. Also, rate interior, sound system, comfort, ride, handling, power, visibility, exterior appearance. WHen you are done with all vehicles that you are comparing, tally the results and let that guide your wallet. I think the cx7 is the best value but thats based on my ratings. Ive seen articles that are comparing the cx7 with the range rover sport and the porshe cheyenne which I think is absurd but Im not a "professional opinioneer" if that makes sense. The cx7 was several thousand less than competitors and rated admirably in all categories.
