I am too old/lazy to "detail" either the exterior of interior of any of my cars (no classics) !
Agree 100%. My son just bought a 1995 Mustang, here in Michigan, that IS in PRISTINE condition ! For the past 25 years (and into the future), it was a "sunny day" car. Garaged when not driven. Not a spec of rust on it. 1 in a million for Mi !
My newest vehicle in an F150. Aluminum body ! I do need to Fluid Film some of the steel under body parts (spare tire mechanism, running boards) before winter get here.
There is a new car was in town. WhiteWater Express. It is a "subscription". $10/month, unlimited car washes.
EDIT : I forgot to mention, they offer
free, self service vacuums, air blow guns, towels and general purpose cleaner
(works good on non-carpeted car mats).
