I'm finally gonna take the plunge and get a new/used car. The verdict is in and the winner is a 1997-1999 Mercedes Benz S420. As for the color, I heard and generally accepted that black on black cars are hotter (temperature wise) inside than other color cars. Is this really true to a significant degree? I've also heard that gold and silver go dull fast because of Ultra Violet rays from the sun. Is that true? My last car (1990 Maxima)was black on black (hence the nickname:"Blaxima") and I swore I would never buy this combination again as it shows dirt, dings and streaks very easily. But that color combo seems to be the most impressive and powerful overall, at least for this model. I know white is suppose to be the easiest to keep clean. I told myself the exterior had to be white but white on black misses the mark for me. White and Tan looks kinda nice but throw in chrome wheels and black trim, you've got enough colors for a rainbow, almost. I perfer the interior to match the extertior to keep the color scheme to a minimum i.e. Based on all this, I leaning towards Black/Black or Grey/Grey. I know some people that swear by Teflon Coating and others say it is the biggest money maker for the dealers and biggest waste of money for the buyer. Someone else told me that clear coat paint makes teflon coating unnecessary. Which is true? Any input is appreciated.
