Starting this summer, Cadillac will allow buyers of the brand’s upcoming Celestiq ultraluxury electric sedan to personalize their vehicles through a concierge service at its Global Technical Center campus.

General Motors will convert a building on the campus in Warren, Mich., into Cadillac House at Vanderbilt, named for designer Suzanne Vanderbilt, who worked on Cadillac vehicles after joining GM Design in 1955, including a 1958 Eldorado Seville coupe dubbed Baroness and the Saxony convertible.

Cadillac will select buyers for the Celestiq beginning this spring, and the first personalization concierge visits at Cadillac House will begin in late summer, the brand said.

“Every Celestiq is personally commissioned and working on-site with our Cadillac designers provides clients an elevated experience,” Bryan Nesbitt, executive director of global Cadillac design, said in a statement. “It’s a unique opportunity to collaborate with our design team, enabling clients to directly translate their vision of their Celestiq into a one-of-one piece of moving sculpture.”
