I got the free mot voucher with my insurance, used it in shirley, southampton branch and car passed no problem. 5 year old scenic that aint been serviced in 2 years and only point they made was back wheels were close to being illegal in next few months. It all depends where you go and if the manager has to get his sales figures up. Its the same story anywhere but if they do fail you are allowed to remove your car and have the defect checked or fixed and return within a set time for a free retest or partial fee.
