Based on 93 used Infinitis we inspected, they are in about average shape — average condition 60/100 vs 61 for all cars we check. Every number on this page comes from real pre-purchase inspections — cars people were about to buy and paid an independent inspector to go through point by point, engine to underbody, paint depth to error codes. Not owner surveys, not warranty statistics, not forum lore: what we actually found.

The bottom line

Treat every Infiniti as a leak-and-body hunt. Get it on a lift first: oil leaks hit most of these engines, with coolant and power-steering fluid close behind, so a wet bay, dripping rack, or worn tires means walk or cut the price hard. Then meter the paint and check the structure—repaints are the norm and structural repairs show up twice as often as usual, so a tidy car can still hide a hit. Scan for live codes before you talk money. They typically hold until about 121,000 miles; past that, only a dry example with a clean structure is worth chasing.
