I've got to say watercolour is not the medium for cars, you have maybe 30 seconds to blend stuff before it just becomes a muddy puddle, I think this is the best I could do in water colours, I should have used oils where I could have spent weeks blending the tiniest detai, that said I'm pleased with with the final result, maybe if I'd used masking fluid to mask the lettering I would have got a better result, but then I've heard of masking fluid tearing paper when removing it.
