When I start looking at cars that I'm not too familiar with I will look at all of that stuff - Edmunds, Autotrader, NADA, KBB, and there's another but if you learn how to read between the lines a bit they are a good way to start.
Truth about it really is - it's subjective to a great degree because no two cars even though the same model are not alike. Different history, records, maintenance, how many owners, paint, interior condition and on and on - you have to develop a 6th sense about it. I have only been able to get in to the ball park with all these car pricing references we're mentioning here. That's good enough cause then you still and will always have to develop an idea of real pricing from studying the market trends as well as condition. Like right now would be very difficult to place an accurate price on something because the market is just fluctuating so much.
Still it must be done and in the end the old addage is will always rule out - your car is worth what someone will pay for it. Or the converse a car is worth what you're willing to pay for it - to you that is. That's how deals are made and lost. It's the art of the deal and some folks have a knack and others don't. Sometimes it works and sometimes it doesn't. Lot's of intangibles in the car buying/selling busines.
That in the end is what makes the search so much damn fun! If I had nothing but time and loads of cash - I'd have a garrage of 30 cars and that would change yearly. I love the search. I love buying and finding cars and having them for a time and selling and getting something new or different. Unless your Leno - if you love cars that's the way it is. Now that I have this NSX - it's a little different - I really, really love this car! So what's on the horizon for me - don't know - no plans - just drive the poo out of this NSX of mine and have fun and oooooohhhhhh what fun it is! Right - can I get an Amen out there....:wink::biggrin:
