Any laundromat owners out there who can help me?

I was wondering if I can get some advice from an experienced laundromat owner. The laundromat that I want to purchase is only $10,000. There are currently 12 Continental girbau eh020's four of them are down, but I can fix them. There are four 40-lb Continental girbau L1040s, one of them is down with an alarm L. There are 24 ADC stacked dryers and about 10 of them are down. The owner has neglected the place for about 4 years because he works 70 hours a week at another job. He overpaid for the laundromat when he first purchased it. He claims the place makes about $40,000 a year gross income. The rent is $1,450 per month and utilities are about $800 a month. He has been very transparent with me and has given me access to the surveillance cameras in the basement to come and look at whenever I please to see how many customers come in on a weekly basis. My main concerns are the machines. They have been used thousands and thousands of times, are they on the verge of completely needing to be replaced? When I opened up the menus up some of the machines, I can see how many cycles the machines have gone through in their lifetime. Some of the machines have gone through twelve thousand Cycles even as high as 17,000 Cycles. They seem to be running fine, a handful of them Shake pretty violently on the spin Cycles towards the end. Do you guys think it is a good investment? How much longer can these machines last if I take care of them?
