Pros
• Flexible schedule • Good for those who like working outdoors • Generally not difficult work. • Interaction with customers can be fun. • Can take home lots of tips depending on where you're working. • Good exercise if you run between cars! • Employees are nice. • Always hiring
Cons
• Extremely hot or cold days make the job much less pleasant • At some locations there are cars that are very messy or smell strongly. • Downtime can be boring if you don't come up with a way to pass the time. • Your schedules are released weekly on Saturdays, meaning it's hard to plan events unless you explicitly request the time from the manager. • Manager sometimes drops the ball on the schedule, requiring some revision during the week. • As far as I can tell, there's not a lot of upward mobility, but the flexibility makes it a good weekend or second job.
