The key is pretty simple. It's hard to confuse the key with anything else and it drives pretty easily.
2006 Volvo V50
I dislike that it lacks in features that a newer car would have. Otherwise it's fine. It is hard to clip a mount onto the air conditioning vent because they slant downwards. I really like that I can see into the trunk and the compartment behind the shift where I can put my phone out of the way. I like how fast it cools up. I wish it got better gas mileage but it still does better than a lot of others.
