Frequently Asked Questions
What is the best year to buy a used Lexus IS?
For value, the 2017 Lexus IS stands out: it sits just past the steepest one-year drop in value, so the first owner absorbed the fastest depreciation, with a typical used asking price around $27,000 — roughly $13,200 below its original MSRP. This is a value-focused pick from observed used-car listings; the right year for you also depends on mileage, condition, features, and budget.
When does the Lexus IS lose the most value?
The steepest one-year drop in our data is between the 2018 and 2017 model years, about 10.0 percentage points of extra depreciation. Buying on the newer side of that cliff lets the previous owner absorb the fastest loss.
Is it better to buy a used Lexus IS new or a few years old?
A IS takes its largest percentage loss early, so a lightly used example is usually the stronger value than a new one — you skip the first, fastest stretch of depreciation. Compare the year-by-year table above and each year's price against its mileage before deciding.
