Depreciation Insight

MG MGB depreciation has traditionally followed classic car patterns: a sharp drop in the first year, followed by a steadier decline. Reliable reports show that the 1978 MG MGB typically loses 15–20% of its value within the first year of ownership. On average, its value settles around 30–35% of the original purchase price after five years, assuming standard maintenance and no major mechanical issues.

  • First year: *15–20%* of original vehicle value
  • Two–to–three years: an additional *10–15%*
  • Four–five years: cumulative *30–35%* depreciation
  • Beyond five years: residual value falls roughly *5–10%* annually

These numbers provide a realistic snapshot for prospective buyers and well‑documented records for seasoned collectors. The MG MGB’s steady depreciation is largely due to its robust mechanical foundations and a steady stream of well‑maintained examples on the market. Keep in mind that extreme cases—such as a car that has undergone full restoration—may deviate from these averages, often commanding a premium in the classic car community.
