What type of components are on the bike? Given the amount of rust on the brake bolt it looks like it may have been stored outside. It could need a fair amount of work to bring up to rideable condition. Expect some drivetrain adjustment screws to be frozen with rust as well.
Another potential issues would be fit (58 is not typically ideal for 5'10"). You'll likely need new tires as knobbies are not ideal for commuting.
$600 seems high.
