1998 BENTLEY TURBO RT MULLINER OLYMPIAN 1 of 1 Hooper Window VIDEO REVIEW RHD 6.75 litre turbocharged V8. This is a one off car unlike any other in the world. 1 of 3 Bentley Turbo RT Olympians ever made. Two were commissioned by Jack Barclay main dealer, one was commissioned by H.R. Owen main dealer. This is the car from H.R. Owen. All three were finished in Twilight Blue. This car had a colour change to what you see here, but remnants of the original Twilight Blue can be seen by the fuel tank in the boot behind the carpet.
