Our Principle

Doing Things Properly

GP Customs & Classics is a specialist automotive studio based under an hour from London Heathrow in Sonning Common, Reading. We are a family run business founded on a single principle: doing things properly.

We operate a fully equipped trimming workshop and detailing studio on-site. We do not outsource our quality. From full interior recommissions to final paint correction, every stage of the process is handled in-house by our own team.

Whether it is bringing tired leather back to life or detailing a vehicle for a concours show, we apply the same rigorous standards of care to every car that enters our workshop.

Our In-House Expertise

Specialist Leather Connolising

We specialise in the proper renovation of original automotive leather. This is not a cosmetic "spray and repair" job. We chemically strip, feed, and professionally re-colour original hides to restore finish and suppleness without losing history.

In-House Trimming Workshop

Handles everything from bolster repairs to complete interior manufacturing using period-correct materials to match original factory specification.

Clinical Detailing Studio

A clinical light-controlled environment for paint depth measurement, multi-stage correction, ceramic coatings, and deep cleansing.

Frequently Asked Questions

For any enquiry about your vehicle, email sales.gpcustoms@gmail.com

Painting is often a superficial cover-up that can crack or peel over time. Connolising is a genuine restoration technique originally developed for Connolly hides. We chemically treat the leather to restore its structural integrity before professionally re-finishing the surface colour. This preserves the original leather, which is what many classic owners require for their vehicles.
