Maybe I was getting another currency, but I was wasting time trying to watch tv, while looking at ebay sc430 highest to lowest price (about 15pgs).
Can someone tell me why there are Toyota Nav. Boxes/Systems for over 6K dollars? A section of the front control console for 4K?
I realize there's a sucker born every minute.but is there something so rare about these parts that they actually think someone will pay more for a electronic piece than they might have to for a whole SC parts/off road use car (one currently is 2K).
I understand people like to spend big bucks on toys for their oy, like 5K wheels..but what is going on...do they just list them high so people will find the parts right below the actual cars (otherwise a buyer would have to scroll down big time to find what they want)??
