We bought our Solara new. We have the 4 cylinder engine with automatic transmission. We now have about 116,000 miles on it, and the only problem, the water pump had to be replaced at 69,000. What a great car, best we've owned. Uses no oil and we get from 23-26 around town and up to 34 on the highway. It's a dream to drive whether in town or highway, smooth and quiet. Still feels like a new car. Plenty of power for highway cruising and acceleration. We've considered getting a new car, but why? Wouldn't be afraid to drive this cross country tomorrow.
Interior and exterior design. Smooth, comfortable quiet ride. Reliability.
Can't really think of any. More power would be nice, but they do make a V6 for that.
