Verify before inquiring
  • This listing has been on market about 6.4x longer than typical for similar vehicles (cohort sells in 10–45 days; this one is at 287). Long days-on-lot on a fast-turn cohort can signal title concerns, mechanical issues, or pricing the dealer won't actually honor. Recommend a vehicle history report before spending more time.
