K & M Auto Sales on Chula Vista's Broadway has been a family-run used-vehicle dealership since 1995, operated by Maricela and Eduardo Becerra across two South Bay locations at 1714 Broadway and 3211 Main Street. Inventory presentation before each vehicle hits the lot includes an exterior wash-and-clay stage that mirrors the surface-prep standards at tunnel operations such as Super Star Car Wash at the Palomar Street and Third Avenue intersection. The dealership sources its domestic and import stock from dealer-only auctions, trade-ins, and wholesale channels, offering buy-here-pay-here financing alongside traditional bank-funded installment contracts for buyers across the credit spectrum. Pre-sale reconditioning includes fluid top-offs, filter replacements, and multi-point inspections handled through the same quick-service pipeline used by maintenance chains such as Jiffy Lube Oil Change for routine interval work. The lot's highest-value units go through a full mechanical inspection covering compression, transmission shift quality, and brake-pad depth before any vehicle is cleared for the retail sales line.
