The sport version is definitely worth the added cost, if you value the ultimate driving experience. At 100K, your suspension is worn but serviceable. A true afficienado would replace the entire front end. At $1,200+ for parts alone, it's pricey but will restore the original ride and handling. I replaced my entire front end at 75K.
The auto is fine depending upon your luck. Some last and some don't. The only maintenance needed is an ATF and filter change.
Ignore the color. Focus on the mechanical aspects of the car when buying a used car. Better to have a car that drives well in an ugly color than one that doesn't drive in a nice color.
