When we buy our next house, a garage is a must - preferably a double. But I have a weekend car and, if possible, I'd like to keep it in a garage along with the tools to maintain it, bikes, and all the other shite and trappings of life. And its a deal breaker
For a lot of people, it won't be, especially if you've got decent off road parking and space for a good size, secure shed. If yours is going to be the only house on the street without a garage, look at whether that's going to make a difference. I'm by no means an expert
