I bought mine new in 1999. 10 years later it's still going strong. 142,000 miles on it now. It had a few issues in the first 50,000 miles, all of which were covered under warranty, a leak in the trunk, the seat heater broke and a leak in the sun roof. right now the only issue is it needs a quart of oil between oil changes and the ABS needs repair.
The look. When I bought it I'd been looking at a black BMW, a Black Lexus, a black Lincoln... bought a red STS instead.
The car is 10 years old, what's there to improve? The newer models are already out.
