Business Expansion: Car Wash+Maintenance

Good day guys, we're planning to expand our business which is autosupply and I'm needing your opinions.
Mag add po kasi kami ng car wash at minor maintenance services (talyer) like change oil, change brake pads etc.
Ang prob ko po is sa car wash equipments, lahat ng nakikita ko sa ibenta mo na :grin: na package is, pressure washer tapos iba pa yung foaming machine while sa ibang bansa ang gamit nila ay pressure washer + detachable foam cannon/lance. May available din po bang ganito satin? at mas okay po ba to kesa dun sa pressure washer and separate foaming machine in terms of durability, etc?

Naisip ko kasi, kung may foaming machine na, tapos 2-bucket method of washing pa, parang masyado na magastos sa car shampoo? parang luge ganon? unlike sa ibang bansa, taas ng pricing nila ng ganitong mga services.

Thanks.
