*Idk if car shop factions are on the table for the new map, but if they are this could be a racket, otherwise it would be at car dealer.*
Add nitrous oxide for cars. It would essentially be identical to the effect of the turbo tune, but cost like 5k and be on a short clock. Obv it would be nice for players that can’t afford the turbo tune, but mainly it would be to test the effect of turbo on a car in case it destroys handling, or just isn’t that impressive.
(yes I know real cars would require a substantial investment into modifications before you could run nitrous. It’s gmod.)
