Macro To Sort Current Tab Worksheet

I basically need a macro to sort the sheet by V, U, T starting from row 3 and ending before the last vechicle. This is the problem though, the last vehicle ends everytime right before Car # in column A. So in other words in this example i would need it sorted by v u t, starting from 3 down to row 12. It ends at 12 because the next line includes car and a number.

Another sheet might have a longer list of vehicles and might end at row 100 before the next line has car number .

It always starts at 3, but the ending is dynamic where it should stop its selection before "car number ".

I would also like it to work on the current sheet im on, because i have up to 100 sheets like this and would not want it name dependant. Just want to click on a tab, and run a macro and have it sort from 3 down to the line before car in column A.............
