What is a good website to look at older used car values?

Trying to look at what my old cars are worth and cant find a good website for it. Some don't go back as old as I have and some want you to give information so dealers can contact you.|||I use three sites pretty regularly and go back and forth cross checking to see whats up. You can try auto trader.com for 90s and newer, or autotrader classics.com for older cars, NADA www.nada.com has new, new used, classics, boats, motor homes tranvel trailers, motorcycles, there is a free consumer section that covers the bases well. Another place on the web is hemmings motor news. www.hemmings.com is an old time online car magazine with deep world wide roots to the car lovers world, there are thousands of links to almost anything car related. there is a want ad section , last months ads are free online, if you wish to view current ads, then you need to pay for the online subscription, or buy the hard copy and have it mailed to your home address. last but not least Edmunds.com is more geared towards new, or almost new cars, but there is a lot of information available. and if you are interested in learning how to go look for and how to inspect used cars, www.samarins.com is packed full of information on how to buy a used car, what to look for, repair histories on used cars and plenty of other links.|||Check NADA.com or Kelleybluebook.com/oldcar
