Without cars, people would be forced to looked toward other forms of mechanized transportation—treadmills, bulls, or gas-guzzling Rube Goldberg machines. Avoid vehicular alternatives with today's Groupon: for $25, you get $50 worth of auto maintenance services or one eco-green oil change (a $49.95 value) at Tonkin Gresham Honda on Southeast Stark Street. Oiling and servicing Portland-area autos since 1960, the Tonkin family's mobile dedication spans more than half a century. Inside Gresham's cleanly styled garage space, skilled technicians doctor cars with basic service treatments ($99.95 for most models), engaging in oil and filter changes, tire rotations, brake inspections, and belt checks. Fluids are checked and topped, and spark-plug replacement ensures vehicles continue lighting up rooms at cocktail parties. Aptly aged autos can benefit from 30,000-, 60,000-, 90,000-, and 120,000-mile services, each ranging from $395 to $595. Eco-friendly vehicles, including hybrid models, retain full dedication to earth-saving endeavors at the hands of service teams that specialize in green cars and oil changes. Beyond its mobile musings, the Tonkin family is locally known for its continued community involvement with local charities, schools, and hospitals, all while providing a dearth of Portland-area jobs as its 21st largest employer.
