Where do I begin?
Late-model Nissan Sentra. I had one as a rental for a weekend. Took it to Pittsburgh and back. Gutless and loud engine paired with a terrible CVT transmission, and I only got 30 MPG on the drives. My ST does better on the highway with about 120 more horses.
2008-12 Toyota Camry. Dead handling, crappy brakes, noisy, slow transmission. I could go on and on.
Chevy Spark. If you sneeze on it, it will dent.
Smart ForTwo. Terrible ride, understeered like a cart, no pick-up and a dreadful single-clutch automanual.
Any minivan.
