Hi, i sold my GT jtd over a month ago to a private seller. He test drove the car for a long time on different roads after inspecting the car first and after.He then agreed to buy the car for less than we had agreed and happily took it away. Anyway i have just received a letter via recorded delivery stating that he intends to take me to court unless i pay for the repair the car now needs. He states that he was very happy with the car for the first week or two, but found the car was smokey sometimes so took it to a garage who found that a hose had split on the intercooler. this was replaced and now he tells me the garsge have advised it may need a new turbo? So he wants me to pay the bill!! the car was utterly reliable the two years i have owned it. it has full alfa history and gave me no reason for concern. should i be worried?
