Solid feel. Door close with a solid thump. Brake feel is the best--don't have to drive Benz, Bimmer, Porsche to know that. Steering effort is light but still retains enough road feel at all speeds--perfect. Smooth running and very quiet on most road surfaces. All these traits spell quality and translate to great value for the money. One gripe--suspension a bit stiff and a little short on wheel travel. Absorbs small road imperfections well but bigger bumps hammer cabin LOUD and HARD.
All the traits I equate with good quality construction and design: Solid feel, Quiet ride, Excellent Brake Feel, Light but Communicative Steering (by contrast, 1997-2001 Camry has heavy steering--heavier than a Honda Accord's), Toyota Reputation for Reliability.
Soften the springs a little bit. It's a sedan, not a sports car. Give it more wheel travel to absorb bigger bumps.
