Hey --- This is Nice.... I do have the paper manual, but it is handy to have it here on my PC, vs inaccessibly inside the car! Ever read the manual while IN the car??
Now... all I need now is the SERVICE manual...
Stop asking me to write more and more cux I don't have time for this and i need the file
