Your car, your notes
A photo of the dashboard warning light helps the shop prepare. Tell the shop about any warning light or sound you have noticed. Say whether the car is drivable; it changes how it gets to the shop. It is powered by the 2.5L 4-cylinder, with front-wheel drive.
What CarmaCars does here
The shop quotes the job; you approve it before any work. You approve the shop's quote before any work. The shop sets the price and the time after seeing the car.
No car? Rent one meanwhile

Good habits for your car
Have the cabin air filter changed on the maker's schedule. Use the grade of fuel your owner's manual calls for. Check that all lights work every few weeks.
A short checklist
Ask whether the estimate includes tax and shop supplies. Ask for the work to be listed line by line on the invoice. Ask whether the shop needs your keys, the wheel lock key or the spare.
