I appreciate that these are not main stream and you need to do a bit of spanner work but don't forget the various Cobras, Jaguar C & D types + the AKSS. For real die hards there is the Ronart.
For those of a dirty fingernail disposition Reg, well made replicas are very desirable. With space and spare money I might have become a collector of replicas. Porsche 917, GT40, Ferrari GTO, & P4. All from my days of reading Motorsport.
Plus the C Type, Cobra, and a real Ariel Atom, & Caterham.
All totally usable, but anathema to both purists and modernists
