2015 Infiniti Q50 vs 2015 Lexus ES 350
Two luxury sedans, compared on what actually matters when you're buying used:
what breaks, when it breaks, and what it costs you.
2015 Infiniti
Q50
6/10
The Q50 is what happens when brilliant chassis engineers and a cost-cut transmission team never talked to each other.
VS
2015 Lexus
ES 350
8/10

Milo scores the 2015 Lexus ES 350 higher — 8/10 against 6/10.

If you buy one, buy this one
✅ 2015 Infiniti Q50
A 2015 Q50S with the 3.7L VQ37VHR (pre-VR30 twin-turbo years) and RWD — skip AWD to avoid driveshaft issues, and the naturally aspirated 3.7 sidesteps the earliest turbo teething problems while still being the sportiest non-turbo trim.
✅ 2015 Lexus ES 350
2015 ES 350 with the Luxury Package or F Sport-tuned suspension, tan or black leather (ages best), and full Toyota/Lexus dealer service history — these were largely unchanged for the generation so focus on condition and records over trim chasing.
