The 1998 Buick Riviera: Car diagnostics
The 1998 Buick Riviera and a diagnostic check: CarmaCars arranges a trusted shop, and never does the work itself. A warning light is the car asking for a diagnostic scan; the code tells the shop where to look.
Your car, your notes
Mention the trim and engine in your request; parts differ between them. Say whether the car is drivable; it changes how it gets to the shop. A photo of the dashboard warning light helps the shop prepare. It uses the 3.8L 6-cylinder turbo supercharged and front-wheel drive.
What to send us
Your request goes to a person, who arranges a trusted shop or gives you its name. You agree the price with the shop before any work starts. Send a request with the car and what it needs; a person replies within one business day and arranges it with a trusted shop or recommends one.
A car meanwhile
We collect the rental when your car is back. Pick a car that suits your week from our fleet. We deliver around Toronto; pickup at our location is free.
Between shop visits
Keep an emergency kit in the trunk in winter. Check that all lights work every few weeks. Use the grade of fuel your owner's manual calls for.
Talking to the shop
Ask what warranty the shop gives on its parts and labour. Ask whether the shop will check anything related while the car is there. Ask whether the shop needs your keys, the wheel lock key or the spare.
When you know your dates
One request: the job, the car, and whether you need a rental meanwhile.
