Pros
If you are just getting out of college and need a job, Enterprise is a job where you don't have to do any heavy lifting and you get to wear shirt and tie. They are on most major job sites and have multiple location in almost every city. They teach you how businesses work and that's not always a good thing. You will have the opportunity to drive a lot of cars, so when you go shopping for cars, you'll know which ones are the good brands to buy. They give the management trainees a lot of decision making abilities and they even manage the car preps and drivers.
Cons
You work. I worked 65+ hours every week. If you are married and/or have kids, this is not the job for you. You also have to lie to customers everyday and sometimes cheat people. Employee have to suck up to the worst people our society has to offer. Don't buy expensive shirts and ties because you will ruin them from all the cars you will have to wash every day. Even if there is a car prep at your branch, they will need help washing cars. The customers you will have treat the cars as if they are disposables. You'll be luck if a smoked out car is the worst you get and trust me it can and will get a lot worst. Lets just say that crack pipes and used condoms were common in cars and they were from white collar corporate customers.
