I have a friend in Lexington KY, who does not have access to the internet, but he has a 1984 Audi 4000s coupe. His cruise control no longer works and he has been told by local mechanics in Lexington that they can replace the "black box" computer controls? for around $1300.00. Does this sound correct? Is there a place that can rebuild this thing? One mechanic in Lexinton told him there was a place in California that will rebuild this unit. <p>Any help would be greatly appreciated.<p>Sheldon Feinstein
