I'll add my 2 cents as I am a relatively new DJ owner. I would stay away from any car with 90K miles on it. Even 50K is pushing it. But to give you an idea with respect to my recent purchase of a DJ Crossroad which could help you.
I purchased the DJ CR, for $18200 out the door with less than 30K miles on it. My DJ has every conceivable option including Full leather seats, Sun/Moon roof etc. Now I went there to buy a Jeep Compass but ended up buying this DJ because she is hot!
So, I don't know what prices you are offered on the two choices but there are a lot of pre owned DJs out there for very reasonable prices and with low miles.
Good luck!
