CarClinic is a problem diagnosis, service history, and running costs package targeted to every car user. You can perform an interactive problem diagnosis tailored to your car's mechanical specification using a database of more than 1,000 common car problems. You can also record your car's service history, fuel usage, depreciation, and so on, and let CarClinic calculate your running costs over any given period. You can do all of this for any number of different cars, once you have entered basic information for each car.

Version 3.2.4 has a new user interface that allows all information to be displayed within a single window, users can now switch between British and United States terminology, and a picture for each car is displayed. Printing and date handling have also been updated.
