My pajero smells quite strongly of dogs (due to having my dogs in it!) and old car. Whilst I'm quite partial to the smell of dogs myself I realise it's not everyone's cup of tea and as I've got my trailer towing course in a couple of weeks I wondered whether anyone could recommend a good air freshener or something that would kill the smell. I'm doing the course in my own vehicle and the instructor will be in there with me for the whole day, so it could be quite unpleasant for him if he's not a doggy person! Thanks.
