Through experience, we've learned that price sometimes has little to do with build quality – to be sure, a $15,000 economy car can be far superior to a $100,000 sports coupe. But, with the 2007 Lexus GS 450h, build quality is on par with its lofty $63,000 as-tested price. Inside we found consistent seams and gaps, panels that were tightly secured and aligned properly, and a complete lack of any squeaks or rattles. The exterior offered much the same, including tight gaps and proper body panel alignment. If there was anything to complain about, it was the seam between the front fascia and the driver's side fender, which was off just enough to be noticeable.
