For a price tag between $32,000 and $38,000, the 2007 Acura RDX proves that fun can be had at an entry-luxury price, while the new 2007 Mazda CX-7 – a very similar vehicle – shows that fun can be had for even less. Imagine – sensible fun – as if there were such a thing. Of course, Acura would rather you not consider the less expensive CX-7.
