We have seen the following updated news in February 2017 from Mark Burley at Quantum Cars via his Facebook page.
Dear Quantum owners we have relocated to Dorset and are able to start supporting spare parts again. The workshop is working on the next demo car which is a mix of old and new Quantum with a 1.8 Zetec on standard ford management to show what can be built on a budget! Thank you for being patient whilst we were sorting everything out!
This is a follow up to the news from June 2016 below.
Due to a change in circumstances rather than continue to provide a limited and unacceptable level of service, Quantum cars is now unable to provide and spare parts for the next 6 months. We are looking to find new premises where we can start providing the parts again in a better manner. We apologise for the change in service over the last 18 months however due to personal circumstances we have had to make this tough decision to actively pause Quantum. We will return in the future with a setup befitting the brand.
See Facebook for the announcements.
The Quantum Owners Club would like to wish Mark all the best and offer any assistance we can.
Meanwhile, the club will try to offer as much assistance to Xtreme owners as we can, while Mark is unable to assist.
