Head to head

Trim-by-trim prices (last 4 model years)

A fair comparison matches equivalent trims, not overall medians. Like for like: at the cheapest common trims, the BMW X3 SDRIVE30I ($33,698) faces the Lexus RX 350 ($49,181); the most common trims on the market are the 30 XDRIVE (37.9% of BMW X3 listings) and the 350 (79.6% of Lexus RX listings); at the top of the market, the M50I ($57,798) faces the 350H ($56,771). Share = portion of the model's trim-labeled used listings (a supply-side popularity signal: what the market actually stocks and sells most). “Cheapest”/“Priciest” mark the ends of the quotable trim range — trim ladders don't map one-to-one across brands, so this is not a factory base-model claim.

Rows are aligned by price position (both sides sorted cheapest-first), not by equivalent equipment — trim names never map one-to-one across brands. Full per-trim detail (price ranges, mileage) is on each model's price page: BMW X3 prices · Lexus RX prices.
