Detailing for the Bonhams Scottsdale Auction
11 Mile Detail Co offers detailing for cars headed to Bonhams' Scottsdale auction, performed personally by AB at a private North Phoenix studio. The 2027 sale is expected in late January, so book early if the car needs multi-day paint correction or a coating. Appointments are limited because one person does the work.

Who this is for
This page is for owners with a European or American car headed to a single-evening resort sale rather than a large multi-day auction. Bonhams offered about 59 cars in 2026, and bidders walk the preview days at close range. That puts the paint, glass and interior under direct inspection before the sale begins.
- Bonhams held the 2026 sale at the Westin Kierland with two preview days, Thursday January 22 and Friday January 23, and the sale starting at 4:00 pm on the 23rd, according to its auction listing.
- Old Cars Weekly reported roughly $11 million in sales for 2026, led by a one-off Bugatti Chiron Super Sport. The catalog ran from a 1957 Mercedes-Benz 300SL Roadster and a 1966 Aston Martin DB6 to a 2026 Porsche 911 GT3 Touring.
- A catalog that spans seven decades puts original, repainted and freshly finished cars side by side. Each needs a different inspection outcome, and some will call for little or no correction.
Preparing for The Scottsdale Auction by Bonhams
Early to mid-November 2026
Send the car's details and photos for an inspection appointment. AB checks paint thickness and defect depth, and tells you whether correction, a lighter enhancement or a detail alone suits the finish.
Late November to early December 2026
Book any 2-Step or Show Correction and ceramic coating early. Multi-day correction and coating need lead time and a held slot, and the coating is done at the studio.
Mid-December to early January 2027
Paint Enhancement, 1-Step, Pre-Trade-In Detail or Complete Detail fit this window, scheduled around your delivery date to the venue.

Confirm your delivery date, then book the interior and glass visit that falls before it.
Studio drop-off
We coordinate studio drop-off and pickup with you and share the address before arrival. Please arrange a ride, as there is no waiting area.
The work that fits this event
- Pre-Trade-In Detail suits a car that will be shot for the Bonhams catalog and then walked by bidders across the two preview days. It can be done at a suitable approved mobile address or at the studio.
- With a mixed catalog from a 1957 300SL to a near-new GT3, paint histories differ widely. Paint Correction removes defects in the clear coat, and on original paint the approach is preservation-first, with some patina left in place.
- Professional ceramic coating is applied at the studio and needs a held slot. It is the service to book first if the car is also getting multi-day correction.
Pre-Trade-In Detail
A Pre-Trade-In Detail prepares your vehicle for a sale or appraisal with deeper interior and exterior cleaning, a full three-pH wash, chemical and mechanical decontamination, engine bay care, thorough vacuuming and stain treatment. Available mobile or at our North Phoenix studio; polishing and headlight restoration are priced separately.
Paint Correction
Paint Enhancement improves gloss with very light correction. 1-Step, 2-Step and Show Correction treat heavier defects at each step up. AB assesses the finish in person before quoting. Enhancement and 1-Step are available mobile or at the studio. 2-Step and Show Correction need controlled conditions.
Complete Detail
A Complete Detail covers the vehicle inside and out: washing, chemical and mechanical decontamination, engine bay, steam and extraction, and exterior protection. AB does the work personally, at your home as mobile detailing or at our North Phoenix studio.
Ceramic Coating
Professional ceramic coating is done at our North Phoenix studio: paint preparation, coating application and a controlled cure. AB assesses your paint before quoting. Choose a 2-to-3-year coating or a 5-year coating; for a lighter, 1-year option that can be done at your home, see Express Ceramic.

Frequently Asked Questions
Book early if you want 2-Step or Show Correction, since those take multiple days at the studio and one person does the work. The 2027 dates are not yet confirmed, so plan from the expected late-January timing and finish correction before your delivery date.
Not by default. AB inspects first and measures paint thickness. If the paint is original and sound, a careful detail and light enhancement may suit it better than heavier correction.
You arrange delivery to the venue as Bonhams directs, and that handoff is yours. Plan the final studio visit for the interior and glass so it falls just before your delivery date, after any correction is complete.
For a Bonhams car, Pre-Trade-In Detail is aimed at the catalog photos and the preview-day walk-around, while Complete Detail is the broader interior and exterior service. AB reviews the car's condition and your delivery date and recommends one when you request an appointment.
Ask about prep for The Scottsdale Auction by Bonhams
AB works on one vehicle at a time, so appointments around the event fill early. Send the vehicle, its condition and the date you are working toward.
