So as far as detailing/car washing is concerned, Ive done a quick search and came up with these:
Loxton Quick 'n Easy Car Wash
Auto bay, manual bays, vacuum and fragrance bays, car detailing service available. Water-wise car wash using recycled water. Open 24 hours, 7 days a week.
Bookpurnong Tce, Loxton.
Ph: 08 8584 5477
Riverland Mobile Detailing
9 Baynes St
Barmera SA 5345, Australia
0407 781 772
I would be happy having my car detailed here, and then just taking it to the DIY carwash up there and do a quick touchup. Or else we could ring that mobile detailer if there is a few of us but not quite enough for your detailer Ben.
