To clarify the rules: it is allowed to enter a word (like Spijkstaal) into Google and check the picture results. In this case you must have an idea (mainly based on knowledge or experience) what the puzzle car might be or how it can be described precisely.
Forbidden is the use of the "Search by Image" (the tiny camera icon) option where you upload a picture (for example the puzzle picture) and you get the results where this very picture can be found on the web. This "Search by Image" has nothing to do with car knowledge, it is just uncovering the picture source by letting Google do the work.
I think without googling in the old-fashioned legitimate way most puzzles would remain unsolved here.
