Do a work up on KBB.com of your car with and without NAV.
That $2550+tax and interest if financed option becomes a paulty $500 on a trade in and if you think you'll get anything close to that $2550+ extra selling it yourself,I think you'll be in for a big surprise.
I will say it's a plus to a potential buyer,though.
I don't have to do a workup on KBB because I'm looking around for a nice 06 LS430 myself. At this point I can look at a price and tell you whether the car has nav or not because the difference is that significant.
I said I SAW the value in the real time traffic, I just somehow have been able to survive the last 5 years having nav without it. Traffic is bad in DC, but its always bad in the same places at the same times so I know where they are. If I get caught in a backup I simply hit "detour" and it gets me around it. No big deal.
Thats fine, but that data is compiled over a nationwide data set which is not applicable to your specific location. Among used Lexus vehicles in metro DC, cars with navigation sell for several thousand dollars more than cars without. Thats a fact. Whether thats the case in Kansas or not I don't care.
Why are you so obsessed with proving me wrong? I disagree with you and you're not going to be able to change my mind. I have no interest in portable GPS units whatsoever, I find them ugly and pointless, and I would never buy another vehicle without built in navigation. Thats just my viewpoint and I'm entitled to it, so leave me alone about it.
