You have so many problems with this car wash yet you keep taking your cars to this car wash. This all sounds a bit like you’re a masochist and secretly enjoy them damaging your vehicles.
2006 focus: mirror ripped off
2018 Mustang: severely scratched paint
???? : damaged sunroof
?????: damaged fin antenna
?????: broken windshield
?????: damaged interior part
is there a reason you keep going to this car wash?
Btw: disclaimers don’t relieve them of all liability for damages. They can’t get out of liability for their defective equipment or their improperly adjusted equipment. They also cannot use a blanket disclaimer to relieve them of all liability. They are offering a service. A customer has a right to rely on their equipment is adequate for the purposes advertised.
They can usually disclaim liability for specific issues. An example would be their equipment is known to rip off typical rod style antenna. If they post a disclaimer for that, they can typically escape liability for damages to rod style antenna.
