selling a blazer

Hello everyone...i am not sure if i am posting off topic or not but I thought I would check opinions here...We have a 2004 Xtreme with 3000 miles and a 2002 Xtreme with about 81,000 we are wanting to sell one of them...the 02 we have the title so in the aspect it would be easier but any good places to list them for sale and what would anyone here pay for these...they both pretty much have all options, moon roof, towing, pw,pw the 02 has front windows tinted the 04 has 6 cd changer and full warranty...i just know id like to get rid of one of them...i have the 04 and my brother has the 02 but that would change if i got rid of the 04..i do have a 2002 camaro which i could make more money on selling but id rather keep the camaro not the blazer...thanks for anyone who replies...i m just tossing ideas around and have never sold a car to a private person before...

owe any money on either of them?

the 04 yeah i do...ive had it since jan...only has 2900 miles on it..
the 02 we have the title my brother ows my mother money but the title is free
