Key takeaways
- Ask how the shop matches multi-stage (tri-coat) colors. Let-down panels and blending into adjacent panels are signs of a careful process.
- Repairs should follow the manufacturer’s published procedures, including any required scans and system calibrations.
- Get specifics on parts: what the shop will use, where it comes from and how long it will take.
- Expect documentation: a written estimate before work starts, photos along the way and an itemized final bill.
- Get the warranty in writing. In Michigan, a shop that offers a warranty must put it in writing and spell out its scope and limits.
A Ferrari, Bentley, Range Rover or late-model Mercedes-Benz isn’t just an expensive version of an everyday car. Body materials, paint systems, electronics and parts supply can all be different, and a repair that would be fine on a commuter car can be obvious, or worse, on a high-end one. Here’s how to tell whether a shop is set up to do it right, from a Birmingham shop known for this kind of work.
Why high-end cars are different
- Materials. Many luxury and exotic cars use aluminum, carbon fiber or a mix of materials in the body and structure. Each has its own repair methods.
- Paint. Pearl, tri-coat and other multi-stage colors are common, and they’re far less forgiving to match than a standard two-stage finish.
- Electronics. Cameras, radar and parking sensors often sit behind bumpers, grilles, mirrors and windshields, right where collisions happen.
- Parts. Some parts are only available through the manufacturer’s network and can take time to arrive.
What to look for
Paint matching that holds up in daylight
A tri-coat finish is built in three layers: a base color, a midcoat (often a pearl) and clear. How many midcoats go on changes the final appearance. Axalta’s tri-coat repair procedure says the first step in repairing an OEM tri-coat finish is a let-down panel, a test panel that shows how many midcoats it takes to match the original. It also calls for a separate let-down panel for each tri-coat color, compared against the car in natural daylight or color-corrected light.
The same procedure notes that tri-coat colors need more area for extended blends than conventional base and clear colors. That’s why a careful shop may refinish part of an undamaged door or fender next to the repair. It’s not upselling. Blending is how the eye reads two panels as one color. Ask the shop how it will match your color and which panels it plans to blend. Learn more about our paint and refinishing.
Repairs that follow the manufacturer’s procedures
Manufacturers publish repair procedures for their vehicles, and a good shop works from them rather than from habit. That matters most for electronics. I-CAR, the collision industry’s training organization, lays out a process that includes a pre-repair scan to record fault codes, a post-repair scan to confirm none remain, and every calibration, initialization or aiming step the manufacturer requires, following its published procedures. Some systems need specialized aiming equipment or a road test under set conditions. Ask whether your car will need any calibrations and how the shop will handle them.
If your car has aluminum or carbon-fiber panels, ask how the shop handles those materials and whose repair procedures it follows.
Straight answers about parts
Ask what parts the estimate calls for (new from the manufacturer, aftermarket or used) and where they’ll come from. For exotic and low-volume cars, parts availability can drive the whole timeline, so ask early what’s on order and when it’s expected. Also check your insurance policy, since some policies spell out what kinds of parts they’ll pay for. At Cole Street Collision, co-owner Ron Karmo handles our estimates and parts.
Careful disassembly and protection
A careful shop removes trim, lights, emblems and handles where the repair calls for it, instead of masking around them, and protects everything it isn’t working on. Ask how the shop protects leather, carbon and other interior trim, wheels and glass while the car is in for work.
Documentation from start to finish
Expect photos at drop-off, during teardown (especially of any hidden damage) and at delivery. In Michigan, a repair facility must give you a written estimate before work begins when the job will cost $50 or more, and you’re entitled to a detailed final bill and the return of replaced parts. If the insurer is paying, hidden damage goes to the adjuster as a supplement. Our guide on choosing your body shop in Michigan explains how that works.
A warranty in writing
Michigan’s Department of State notes that a repair facility doesn’t have to guarantee its repairs, but if it does, the warranty must be in writing and disclose its scope, including any limitations. Ask to see it before you agree to the repair. At Cole Street Collision, all of our work comes with a lifetime warranty.
One person you can reach
You should know who your contact is and how you’ll get updates, especially when parts are on order or a supplement is pending. Cole Street Collision is owner-operated: Ron handles estimates and parts, and co-owner Dorid Stermasi oversees the work in the shop.
A track record on cars like yours
Ask to see finished work on similar cars and colors, and read what other owners say. You can see examples in our work and read customer reviews.
Questions to ask any shop
- Have you repaired this make and model, or this type of paint, before? Can I see examples?
- How will you match my color, and which panels will you blend?
- Whose repair procedures will you follow, and will the car need scans or calibrations?
- What parts will you use, where will they come from, and how long will they take?
- How will you protect the interior and the parts of the car you aren’t repairing?
- Will I get photos of hidden damage and a copy of every supplement?
- Who will be my contact, and how often will I hear from you?
- What warranty do you give, and can I have it in writing?
Red flags
- A verbal price with no written, itemized estimate
- “We’ll match it” with no discussion of blending or test panels
- Vague answers about parts or repair procedures
- Pressure to authorize work before you’ve seen the estimate
- No written warranty
You can also confirm that a shop is registered with the state using the Michigan Department of State’s dealer and repair facility listing.
Insurance and your choice of shop
Your insurer may suggest a shop from its program, but in Michigan you aren’t obligated to use it. The law says insurers can’t unreasonably restrict where you have your car repaired (MCL 500.2110b). If you have a specialty or collector policy, read how it handles repairs, parts and shop choice before you need it.
