Most likely. The only way they would be able to narrow it down like that without removing the rear wheels (something totally unnecessary for an oil change) is by trying the handbrake. If you have a stick-shift, they might need to use it, but read on… I have done a few brakes in my time and it’s never taken me more than 30 minutes or cost me more than $30 for pads/shoes. At $165, that goes beyond scam and borders on sodomy.
