Very simple, especially if you read the instructions. If you’re out most of the day, you likely won’t be bothered by the nearby train, even if you’re somewhat sensitive to sound. If you’re utilizing the parking, a car on the smaller side is better but not imperative. My car is easily on the longer/wider side (S14 Silvia) compared to other Japanese passenger cars, and it still fit. Also, a ¥2000 Suica card will get you a long way during your trip.
