I'd say you've likely make a wise move. HHRs don't really hold their value very well and maintainence gets more costly as the mileage builds especially once you've reached the point when you no longer have a warranty. In our case, by the time we're nearing 100K based on how it's been driven up to now, ours would be about 9-10 years old. But it will be long gone by then since we plan to sell/trade within the next year or so.
