I have a new 2012 MB ML350 in "Diamond White" that cost $60,000. The special tri paint alone was an option of over $1,500. Not that that is a tremendous amount of money for a car these days but certainly not a cheap car either. I do not take it out if it is raining. It sits in the garage every night. I only put about 8,000 miles a year on a car.
Each time it is used I wash the windshield, check for bug guts and clean them off using 1Z Einszett Anti-Insect spray, vacuum the interior, etc. I wash it weekly with ONR or Duragloss with AquaWax waterless washes. It gets the foam gun once a month followed by Griot's wash or sometimes CG Clear shampoo - and always using the CarPro Merano wool glove; usually followed by periodic toppers of Optimum Spray Wax, AquaWax or 1Z Einszett Spray Wax, whichever is closest at hand at the time and whichever strikes my fancy. Glass is polished with the Griot polisher using their 6" white glass pad and Duragloss Nu-Glass polish, finally topped with AquaWax.
For complete details every few months the car is washed with CG Clear, clayed (Griot's mild clay using Griot's Speed Shine lube), washed again, polished with P21S Paintwork Cleanser using once again Griot's 6" polisher. The engine bay gets swabbed down with P21S Total Auto Wash followed with a coat of Protectant 303. The paint is finally sealed with a Duragloss combo of 601/111 followed by two coats of Collinite 845 wax. Wheels are cleaned with CG Diabolo and sealed with a coating of Klasse AIO or AquaWax; tire dressing is Meguiars Endurance. Interior is cleaned with Griot's Interior Cleaner and dressed with Protectant 303; all exterior black rubber trim gets a coat of 1Z Einszett Vinyl/Rubber Car Protectant Tiefenpfleger.
To give detail to what Bill just said: I was lucky enough to have retired when I was 47 years old in 1995. I have lived on a golf course in a country club since then and have put more miles on my cart than I have my cars. Am I wealthy "with money", as you put it? Well, to a man living in a box under a city bridge I suppose I am. To a man like Perot, Forbes or Gates, I am mere pocket change. So young man (and I assume you are young or you would not have asked such a question to begin with), wealth is really all relevant, isn't it?
I do not consider myself "wealthy", but I am doing okay. Rest assured (as I think you can gleam from the above), that no matter how you define it or what you consider "having money" or exactly what a "high dollar car" is all about, my ride is NOT and never has been - neglected. And yes, I do ALL the work myself.
