As you say, it is a lot of money to part with if you aren't 100% sure about getting one. Perhaps worth sleeping on it and seeing how you feel. If you do decide you'd like one, then at least you know that is a very good one. I would recommend going to see the 200 as well - that way you have something to compare the 197 with, give it all a bit of perspective.
As above, the cold start shouldn't be a deal-breaker, as they are all like that. However if that's one of the factors that puts you off personally, then you can't ignore it - you have to take everything into account.
