Incredible car! Soft ride, low maintenance, good mileage. Only complaint - after 13 yrs of a gray 86 Camry and 11 yrs of this silver 99 Avalon, I feel the need for a change. Could be midlife issues. I need something bright and irresponsible. But seriously, GREAT CAR! Fits all sizes of people and luggage. Surprisingly good mileage for its size and comfort and I highly recommend it. That's what makes it hard for me to give up.
Space - headroom, legroom, hip room in front and back. Soft ride, good acceleration. Low maintenance cost. Good mpg with non-premium fuel.
A little late for 99 model. As someone else noted, many nice-to-haves didn't technologically exist in 1999. One flaw, corrected I think in 2000 was lack of cup holders and ac/heat vents in back. Serious miss since size of backseat area makes this a prime car for groups not wanting a minivan.
