Sinister Autoworks

Took my S4 in for a one stop shop, got all maintenance out of the way along with stage 3 upgrades. Bill is super easy going and very knowledgeable about B5 S4's. Turn around time was quick and the work is phenomenal, he addressed any potential issues to ensure that the car is at 100% I would highly recommend Sinister to anyone looking for good work at a reasonable rate.
