Rough example of the GTX spotted for sale online in Oct 2023, asking $8,500. Needs a lot of body work and hasn't been well looked after it seems, but could be restored back to original condition if you threw in another $10k.

Seller noted the following at the time it was advertised: It's over 90% complete, the engine runs very well and the gearbox has no issues. Would need slight repairs to make road legal (new rear seat belts etc). NOS bottle and spray system is installed, never used and needs finishing touches to make work. Adjustable sports shock absorbers, slotted brake discs and sports steering wheel. The body and paint is not in showroom condition. Please see photos! Body has several dents, some rust patches in rear quarters. Paintwork is very average and varies from panel to panel.
