They are very nice if pricey.

 

There's a secondhand set on the JEC website at a relatively favourable price, £1250 for four, but they are 15X7 inch, a bit wide for most of us.

 

The Ogle perforated ("Pepperpot") wheels from the Series III saloons have a similar look. They are 15x6.

 

hmmmm….that car looks familiar….1992 V12 VDP in Black Cherry. ☺️

 

I seem to remember you owning such a car Prof., of many you owned over time, built for Canada only, This particular car is #92 of the last 100 of this model built. Now resident in Beijing.

 

This is getting off topic but all 3 photos are of the same car, and they show the complex nature of the Black Cherry colour in different lighting. Yes, it is the car now in Beijing. I loved it and owned it for 12 years.

 

FYI,
You can get custom off set wheels both in modern styles as well as classics like the Dunlop style racing wheels in any size. As an example my 63' Jaguar 3.8s came stock with 5" wide wheels with skinny 185's, I measured the space available after I changed the car to custom coil over suspension upgrades, converted it from knock off's to 5 lug, which by the way turns out to be the same bolt pattern as standard Chevy wheels and I was able to now run a 17" x 8.5" wide wheel on all four corners with no flares at and am running 245 wide tires with no issues.

Here is an example of even classic style Dunlop wheels you can get in 14", 15", 16", and 17" with widths up to 16" wide, https://www.imagewheels.co.uk/billet-46-alloy-wheel/ They are better than the originals as these are lighter weight and you can get any custom off set so you can put the maximum width wheel that your setup can handle!
