Car Unlimited operates a small independent dealership in Chula Vista's Third Avenue Village district at 1545 Third Avenue, south of the Palomar Street intersection. The lot stocks a rotating selection of used sedans, coupes, and SUVs, with maintenance referrals for post-purchase oil changes directed to nearby quick-lube providers such as Valvoline Instant Oil Change. Each vehicle undergoes a pre-sale OBD-II scan, brake inspection, and fluid-level check before it reaches the sales line, and buyers receive a current smog certificate at delivery. The Third Avenue location places the lot within walking distance of South Bay transit stops, and buyers needing temporary transportation while a purchased vehicle is prepped can coordinate short-term rentals through providers such as MC Car Rentals. Pre-delivery reconditioning includes headlight-lens restoration, tire-pressure calibration to door-placard specifications, and battery load testing to confirm cold-cranking amp ratings meet manufacturer minimums.
