Car diagnostics: how we help
CarmaCars does not do this work itself. For a diagnostic check on the 1985 Buick Riviera, we arrange it with a trusted shop or connect you with one. A warning light is the car asking for a diagnostic scan; the code tells the shop where to look.
Details the shop needs
The shop sets its own price and time after it sees the car. A photo of the dashboard warning light helps the shop prepare. If you have the service history of your Riviera, have it ready for the shop. It is powered by the 5.7L 8-cylinder, with front-wheel drive.
What to send us
You agree everything with the shop before work begins. The shop quotes the job; you approve it before any work. You approve the shop's quote before any work.
Keep moving meanwhile
Pick a car that suits your week from our fleet. The rental is priced like any other on our site. We hand every car over in person, at your address or at our location.
Before the shop starts
Ask how the shop will contact you if it finds something unexpected. Ask for the work to be listed line by line on the invoice. Ask the shop to call you before doing anything not on the estimate.
Car care, briefly
Clear snow off the whole car, roof included, before you drive. Have the battery tested before winter if it is more than a few years old. Wash the underside of the car in winter to clear road salt.
