At 3651 El Cajon Blvd in the 92104 corridor, North Park Auto Sales & Service traces its roots to 1996 when the operation launched as an auto repair shop on 30th St before expanding into pre-owned vehicle sales in 2016. Every vehicle listed for sale receives a multi-point mechanical inspection, and buyers needing cosmetic reconditioning can arrange interior and exterior detailing through Rivas Auto Detailing on El Cajon Blvd. The repair side of the business handles tune-ups, oil changes, brake service, AC recharge, and engine diagnostics for walk-in customers independent of the sales operation. Shoppers comparing pre-owned inventory across North Park's El Cajon Blvd corridor can also browse the selection at Bancroft Auto Sales near the same block. The shop's most complex service offering involves rebuilt Subaru EJ-series boxer engines, supplied and installed for high-mileage Outback and Forester owners facing head-gasket failure.
