questions to be asked to seller - Car Wash Forum

Hello,

I`m going to see existing self serve car wash. I`m kind a newbie. I have been talking to a seller for last couple of months. as a being a new owner what questions should I ask to the seller.
he has already showed me his P&L, gave me a tour of his carwash also showed me how to operate all the machines and ready to give me a training for first week and after incase I need to ask anything.
Thank you Take the P&L with grain of salt. They can be easily cooked to show whatever the owner wants. Ask to see 3 years of tax returns.

How old is the equipment?
Does he have maintenance records?
Is the manufacturer still in business? If yes, is it a model that is still supported by the manufacturer?
Is there a reliable service company close by because I've seen more than once a seller say they will be around to help after close of sale and then disappear. A week of training is not even remotely enough.

thank you for reply
he just sent me two yrs tax return.
and gave me the numbers of all techies who come and work on the machines. but I will still ask him about support of manufacturer and one or two additional weeks of training.
thank you
I got one day. LOL. A week would have been awesome.

What's to learn? You just show up a couple times a week, empty the trash, check soap levels, and collect your piles of cash. I saw it on youtube so it has to be true.
and gave me the numbers of all techies who come and work on the machines.

If he's having to pay techs all the time that tells me he wasn't making money(techs are expensive) and he wasn't hands on much at all and probably can't teach you much. I wouldn't be stunned if some of those techs jack-legged a lot of things.

I will still ask him about support of manufacturer and one or two additional weeks of training.
thank you

Nope. Get the manufacturer and model numbers off all the equipment yourself. Get some pictures if possible also. Contact the manufacturers yourself. I've had more than a few buyers take the owners word for it, called me for support after the purchase, and were not happy when they found out that the equipment was long obsolete.

The Ugly

You can find more information on our web, so please take a look.

Keeping it clean.

When you enter the car wash business, it is an invitation to the public - hereafter known as your customer base - to come and leave all their dirt and trash at your location. You'll get some money and they'll get a clean, dry and shiny car.

In the car and truck bays, the average customer will leave little to no mess at all - but the ones that do will leave you seriously shaking your head. From mounds of mud, leaves, animal carcasses, feces, motor oil and more, some of your customer base will use your car wash as a public dump ground - while they leave with a clean truck bed, trailer and vehicle. In the vacuum area, it's even more fun! Some customers can fill a 55-gallon trash can all by themselves. This area, if not attended to regularly, can quickly turn your new, clean business into an unsightly, and possibly unsanitary, mess. It is not uncommon to work hard to make your car wash a sparkling clean location, only to return in a couple of hours and wonder where the trash bomb came from in your absence.

Many new car wash owners find this disturbing, but to the Old Guard, it's just the price of doing business. The best and most successful owners are sticklers for cleanliness. Their customers know it and that's one reason why they return over and over again. The full-time owner is constantly working to keep his place clean. He or she watches for these problems and tries to stop them before they occur. If you are going to be an absentee owner, be sure to hire someone that really cares about cleanliness and customer service. Keeping the grounds clean is instrumental in customer retention.

Vandalism

In ancient Roman times, the Vandals were a nomadic people that invaded and pillaged Rome. Today they are local good-for-nothings that destroy private property for little gain - or just for fun. Yes, your car wash will be hit by vandals. Change machines, vacuums, meter boxes, hoses, guns and more - the list of what can be damaged is long. The unfortunate thing about vandalism is that it usually costs more to repair the damage than the amount of loot the vandals stuffed in their pockets.

The Bad

Maintenance

On a beautiful Saturday, when people pass the car wash and see a line of people waiting their turn, they may think: "Wow, that looks so easy and cheap to get into." They don't see the behind-the-scenes chaos of pumps, motors, solenoids, compressors, electrical panels and computers all working in unison and coordination to make their car wash experience seem so seamless and easy. They know little and care less about your maintenance costs.

Car washes are big mechanical machines and big mechanical machines need attention because they incur normal wear and tear damage. Preventative maintenance is the key to success here and the most successful operators have a maintenance plan in place and a plan of action in case of emergency.

Where a lot of new self-service car wash owners fail is the basic maintenance of their new acquisition. Most of these facilities have been around for a long time, some as long as 40-plus years. The equipment is probably just as old, but the prior owner knew how to maintain it and keep it running smoothly.

When car wash bays and equipment are down, customers take note. It doesn't make a good impression when something breaks and the owner doesn't fix it pretty quickly. I've seen many owners start their decline by thinking it's just one bay, I'll take care of it later when I have more money. Then, bay two goes down. Revenue begins to decrease and then another bay goes down – thus begins the cycle of death of the business.

Customer Complaints

"Look what your car wash did to my car!" "The soap's not strong enough!" "The soap's too strong!" "Your foam brush isn't thick enough!" "Your foam brush is too thick!"

I could go on and on.

You'll have to be prepared to deal with grumpy customers who may or may not have legitimate complaints. Help the ones you can, but remember: not everyone is a good customer. Learn who your regulars are and encourage them to keep coming back.

The first year is the hardest for the new owner. The Ugly and The Bad parts of the business can be alleviated with proper knowledge and resources as you enter this new endeavor. Learning how to successfully run a profitable self-serve car wash means:

  • Dealing with the public - otherwise known as your customer base. Grumpy, dirty, messy and sometimes hard to please, the lucrative owner either does well with the public - or has someone in place who is happy to be the public face.
  • Maintenance - Equipment maintenance is a must! It can be frustrating, especially if you are not mechanically inclined. If your attendant can't work on the equipment, you'll need to have a trusted and competent distributor you can rely on to keep your systems up and running.

Absentee owner - If your plan is to purchase a self-serve car wash as an absentee owner, then be sure to hire the necessary people to staff it and fix it when necessary.
