many questions arise from this...
How much, if you do, owe on you GT? Miles? Mods?
How much you getting the cobra for? Miles? Mods?
I say if you dont owe anything on your GT do not get rid of it.
If you owe $ on it I guess it depends how much and for how long.
Also even though you may have a stable job with stable income always take into consideration this bad economy and what effect it can have on you personally in the future.
I for sure wouldnt want to get into paying $390-$500 a month when I can just fix up my paid off GT
imo
