MG MGB Depreciation Overview

Classic sports cars tend to appreciate or hold their value once they cross a certain mileage milestone. However, newly marketed units still experience a typical first‑year loss due to immediate wear‑and‑tear and the fact that many buyers seek a well‑maintained vehicle. A realistic early‑stage depreciation range for a used MG MGB price is:

• First year after purchase: 15‑20 % drop in resale value, primarily driven by high mileage and mechanical wear if purchased from a dealer.
• Next three years (2‑4 yrs): 8‑12 % annual depreciation, assuming normal maintenance and moderate mileage.
• After 5 yrs: Depreciation slows to 3‑5 % per annum as the vehicle enters a stable collector market segment.

Notably, the MG MGB depreciation curve is more linear than the sharp first‑year dip seen in standard domestic cars. Buyers often accept a slight depreciation for fresh models, which can offer better reliability and fewer maintenance surprises.
