Pros & cons

- Outstanding reliability, among the most dependable luxury sport sedans
- Excellent resale value and low repair costs for the class
Cons
- Premium fuel recommended
- Turbo IS 200t/300 four-cylinder is merely adequate; firm F Sport ride
- Tight rear seat and small trunk versus rivals
- Aging infotainment with a fiddly Remote Touch trackpad on pre-2021 cars

The curve's data ends 10 years in, so the line levels off after that. Treat the tail as a floor, not a forecast: asking prices for older cars depend mostly on condition, mileage, and the current market, and often sit well above it.
