Built in 1969 this Mark II, MGB roadster is one of the last chrome grille models made. It is fitted with the later gearbox with synchromesh on all four gears and overdrive on third and fourth gears.

History of SNV 650G:  

 

Extensively restored during 1995/96 during which time it had new front wings and a new door fitted and was re-sprayed tartan red from its original yellow.  The windscreen surround was rebuilt and a new windscreen fitted.  The engine was rebuilt and the gearbox and overdrive were replaced.  The speedo was zeroed at this time so the mileage shown is genuine for the engine and gearbox.

 

It was re-sprayed again at the beginning of 2006. The interior has been re-trimmed in black with red piping and the original vinyl seats rebuilt using new seat foams and backs and re-covered in black leather with red piping.  The hood and frame have been replaced and the hood has a zip down rear window which is non-standard for its age.
