well as far as trade ins go you'll get a shocking price for it. i had an 07 T30 X-trail STS-Xtreme that was i paid 29k (32k with no options retail) for nissan employee price and had it for 4 years and put 95k on the clock and about 10k worth of suspension, exhaust, engine mods and stereo, thing was immaculate and had service history of every 5k service and got offered on average about 13k for it and the lowest i got offered was 9k. i ended up getting offered 18k but pulled my subs and amps out. i would have sold it privately but i found the stagea and made an offer so it had to go asap. its now sitting on a used car lot with 24.990 on it and they removed my $800 alpine headunit and replaced it with a $120 alpine unit, idiots.
i wouldnt trade it unless your that urgent to get rid of it
