The problem with a collection

Cars that sit still
still get worse.

A collection doesn't degrade the way a daily driver does. It degrades quietly. Dust settles and bonds. Humidity swings leave water spotting on paint nobody has touched in four months. Leather dries. Coatings stop beading. Then one day you want to drive it, show it, or sell it — and what should have been an afternoon becomes a week of correction work.

Calling a detailer each time a car needs attention is how that happens. A planned rotation makes routine upkeep easier to manage, with additional correction work assessed separately when needed.

The Program

Built around your
garage, not ours

We start by walking the collection with you, then build a rotation. Every vehicle gets seen on a schedule that matches how it's actually used — the ones you drive get more attention, the ones under covers get the right attention.

Scheduled Rotation Detailing

The core of the program

Each vehicle comes up on a set interval. Dust removal, safe wash where appropriate, interior and glass, and a walk-around that catches problems while they're still small.

  • Per-vehicle interval set with you
  • Safe dust and contaminant removal
  • Interior, glass and trim upkeep
  • Condition notes after every visit

Storage & Dormancy Care

For the ones that don't move

Cars in long-term storage have their own failure modes. We handle the ones that live on the surfaces — water spotting, bonded dust, drying leather, and cover-related marring.

  • Water spot prevention and removal
  • Leather and interior conditioning
  • Safe cover handling
  • Pre-storage preparation

Coating Maintenance & Renewal

Protecting the investment already made

If cars in the collection are ceramic coated or have PPF, those need maintenance washes and periodic topping to actually deliver their rated life. We track which cars are due.

  • Coating-safe maintenance washes
  • Topper and booster application
  • PPF care and edge inspection
  • Per-vehicle coating records

Where this ends and restoration begins

Maintenance here.
Correction over there.

This program supports routine upkeep across a collection. When a car does need real work — multi-stage paint correction, wet sanding, orange peel or overspray removal, Barrett-Jackson auction prep, museum floor preparation — that's our restoration side, and it's quoted per car.

FAQ

What collectors
ask us first

How is this different from your classic car detailing page?
Our classic car detailing service is project work — multi-stage paint correction, wet sanding, auction and museum preparation, done on one car at a time. Private Collection Care is the opposite shape: a standing, scheduled program that keeps an entire collection presentable year-round. Most collectors end up using both — correction once, maintenance forever.
How many cars do I need for this to make sense?
There's no hard minimum, but the program is built for garages of roughly four vehicles and up. Below that, our Household Membership may fit better. If you're on the line, tell us what you have and we'll say honestly which one is the better value.
Do you come to my garage?
Yes. Our units are fully self-contained — we bring water, power, and commercial equipment. We work in private garages, storage facilities, and climate-controlled collection spaces across the Portland metro. Nothing has to be driven or trailered to us.
Can you work around cars that rarely move?
That's most of what this program is. Vehicles that sit collect dust, develop water spotting from humidity swings, and get interior odor and leather drying. A scheduled rotation catches all of that before it becomes correction work.
Do you sign NDAs?
Tell us about any confidentiality agreement or photography restrictions before scheduling. We will review the requirements with you and confirm the arrangements before work begins.
What does it cost?
It's quoted per collection, because a six-car garage of daily-driven moderns and a twelve-car garage of concours cars are completely different jobs. Text us what you have and we'll build a program and a monthly number around it.
