Arranging the work for the STS
Need an emissions test for your 2008 Cadillac STS? We do not do mechanical work, but we arrange it with a trusted shop and keep you driving meanwhile. Rules on emissions testing differ by province and state.
Your car, your notes
If you have the service history of your STS, have it ready for the shop. Bring the owner's manual or service records if you have them. Tell the shop about any warning light or sound you have noticed. The 3.6L 6-cylinder, paired with a 6-speed automatic, drives it.
Our part and the shop's part
Your request goes to a person, who arranges a trusted shop or gives you its name. We can deliver a rental to you while your car is at the shop. We do not set the shop's price or promise a date.
Keep moving meanwhile
Rent by the day or the week, and stop when your car is back. Add a rental to the same request as the repair. We meet you with the car at the time we confirm, at your address or ours.
What to ask
Ask whether the estimate includes tax and shop supplies. Ask what warranty the shop gives on its parts and labour. Ask whether the quote includes both parts and labour.
Between shop visits
Clear snow off the whole car, roof included, before you drive. Wash the underside of the car in winter to clear road salt. Check that all lights work every few weeks.
One more step
A short request starts it: the car, the problem, and when suits you.
Request emissions test
Tell us when suits you. A person replies within one business day and arranges it with a trusted shop or recommends one; the shop sets its own price and time.
