Not including the 1990s revival RV8 model manufactured by Rover, MG Cars manufactured and sold slightly more than one-half million units throughout the world. Collectors should note that the revival models have less than 5% parts compatibility with the original MGB. Therefore, they are a difficult car to possess due to the rarity of the parts. Automotive historians estimate that one-third of all MGBs manufactured remain today, which amounts to approximately 150,000 worldwide. This explains why they are so hard to find, and why they can be so pricy when one does manage to find an MGB for sale.
