Bill the Mechanic

Bill the Mechanic and his successor Bill the 2nd (Mechanic) are the local mechanics in Pine Lake and Pine City. The player can visit them to repair or modify the Time Machine.

Shop
The kind of work Bill offers is repair jobs, a hover conversion upgrade, and different variations of the Time Machine. You can change the tires, headlights, reactor placement, and color.

The layout of the shop includes a parking spot for the Time Machine to be parked for modifications, a bookshelf, an Item Box used to store objects in your car's inventory when switching reactors, a desk which supports Bill's computer and keyboard, and, from 2007, a large robotic arm presumably used to aid in modifying the car.

History
Bill's Garage apparently starts operating in Pine Lake in 1940.

In 2007, Bill's Garage has been upgraded. There is now a hologram sign advertising hover conversions (although the player isn't able to purchase it yet). Inside the garage, a robotic arm and some light gray crates were added.

In 2010, Bill has retired. Bill the 2nd takes over the operation of Bill's Garage. Hover conversions are now available for the player to purchase.

In 2045, Bill the 2nd reopens a garage in Pine City. He now offers a no wheels hover overhaul. Other than upgrading the hover capabilities, he no longer modifies cars. Due to how much time has passed, he now appears very old with gray hair and a mustache.

Act III
During the quest The Last Stage, Edward pays Bill (the first) to help him make the Time Machine capable of diving underwater, though Bill just calls the upgrade "anti heavy rain sealment."
