GTA 4 quest stuck - what am I supposed to do?

GTA 4

I am on the Clean Get-away mission where i have to do the following:

Objective: Find and take the silver Blista Compact.

Locate the marked Blista Compact on the map. Found Jimmy cleaning the car as I approached. Read the tutorial on the stun punch and greet Jimmy with one. Got inside the Blista Compact and drive off.

Objective: Take Jimmy's car to the lockup.

Ok so i stun-punched the dude, got in the car and followed the map to the location of the yellow marker. Once I arrive, there is no mission arrow or anything visable anywhere that indicates what must be done next. In fact i am sitting right ontop of the yelow mission marker!

I even called Vlad on cell and only get a answer msg. Nothing on the radar map is indicating what I need to do either. Is my game screwed at this point?

Any ideas what I can try next are very welcome! :)

Theres a cleaning garage or something close the Blista if I remember correctly. You have to wash the Blista.

the same problem accur with me too I will reinstall the game, willnot setup the patch and see what will happen
