Express - Rent A Cheap Car in downtown San Diego's Middletown, in continuous operation on Kettner Boulevard since 1996 with a BBB A+ rating, maintains a 300-plus-vehicle fleet from its Middletown lot near the historic Santa Fe Depot. The independent structure accepts foreign driver's licenses and debit-card deposits on all vehicle classes, a booking flexibility that the corporate-chain counters at the nearby Hertz Car Rental - San Diego Downtown branch on Kettner do not match. Drivers under 25 can rent convertibles, sports cars, and minivans with an age surcharge rather than an outright refusal, opening the fleet to university students and young international travelers. Weekly and monthly rate tiers serve SDSU and USD students who need semester-length transportation, and the same long-term pricing extends to production crews filming across San Diego County. A 300-car fleet at this volume requires a fixed tire and oil rotation schedule, and the Middletown corridor's density of quick-service bays — including Evans Tire downtown — keeps that maintenance loop inside the 92101 zip. The most complex rental packages combine multi-month leases on passenger vans for church groups and nonprofit shuttles serving the Balboa Park corridor.
