My mother-in-law's Renault Twingo Play (2015 plate), with 5,000 miles on the clock, has sat in her garage for two years. It has only been used for 100 miles in this time due to a combination of old age and the pandemic. My son (her grandson) is thinking of buying it from her. Can you advise please whether by not being used this will have damaged the car? Many thanks for your advice, Kind regards, David Moss
