You are very correct on that .. Buddy this is the condition of our workshops in Peshawar no matter what we do you come back to find the car in a very dirty shape ...
But all said .. right now the car is in the the phase where we are trying and testing every thing tht it fits properly .. the dirty engine you see installed is NOT the actual engine but just a mock up engine which is there to help us make proper foundations on and adjustments etc ... also in the interior since we changed LHD to RHD so alot of fitting and fitting adjustments was required .
Once every thing is done the mock -up engine would be pulled out along with all the interior and the all the paint would be stripped down .. after that body work would be done ... InshAllah once its all clean then painting would be done in a proper Paint booth etc and at the end a Fresh V8 would be installed
So don't worry about it being dirty it in very intial phase 
And thanks for your comments
