In my experience a "specialist" in a marque is trading on having good knowledge in a specific area, normally charging a premium for that implied knowledge/experience. Trading as a specialist when you sell vehicles with known problems that are common to type of vehicle takes being a bad trader to a lower level. Even worse is when said specialist liquidates the business to avoid his unhappy customers perusing justifiable complaints but then has the nerve to start up a company immediately under a slightly altered name making the same specialist claims from the same address using the old companies website. That is not just a bad dealer but the lowest of the low CON MAN.
