The ride looks great mate and myself i like the G35 V35 where i live.Keeping clean a black car is a pain ,i own a white car and a great example is where i live i washed and waxed it the other day and within two hours it was covered in dirt but as said you expect it as where i live it is always wet and atm gritters are spreading grit and salt all over the roads which just get sprayed up.
I see a point if you have gone out to take the pics then it would look great if you cleaned your car, but sometimes you are in the right place for some pics of your car with a great back drop and it wasn't planned so it can be spare of the moment pics where your ride is not in show condition.
As for stock cars where i live there is just as big scene about keeping cars stock as there are modding them,if there a year old then it does not really count.A popular one is old Civics where folks are restoring modified parts back to stock parts.
