A survey conducted by "Auto Express" magazine in August 2006 reported that 745 of the 807,000 Marinas sold in Britain were still on the road, fewer than one of every thousand sold, making it the most-scrapped car sold in Britain over the previous 30 years. The low survival rate is due to a combination of factors, chief amongst which is the Marina's poor rust-proofing. Like other family saloon cars of the period, the Marina did not gain the status of a classic car, whilst large numbers were still in good enough condition to encourage preservation. The Marina also made a good donor car for several other British Leyland models. The brakes and suspension from a Marina were/are often used to upgrade the Morris Minor, whilst the A and B-Series engines were used in a wide variety of other cars. The 1275 cc A Series, for example, made an easy performance improvement for a Midget or Sprite, whilst the twin-carb B-Series engine used in the TC versions of the Marina fitted the MGB without any modifications needed, and the TC engine carried a slightly higher power output. Factors such as these meant that elderly Marinas were more likely to be stripped for parts to upgrade more popular models than to be repaired or restored.
