Don't feel too bad. I am in your same boat. I am in a 5 year lease and it is my only ride too. I deliver pizza in it and now have close to 60K miles on it and i have 2 years left on the lease!!! AHHHHHHH!!! What am i going to do? I dunno know, i'll cross that road when i get to it. My advise is to just enjoy it as much as you can. Leases are difficult to get out of.
I've also done lots of mods, sunroof, Sony stereo (much better than stock), lift w/tires (which i have chosen to take off here soon). I figure that i won't be able to turn my VX in at the end of lease because of all the miles i put on it, i might as well put the money into buying it.
