Trying to decide whether or not to sell the mustang

Ok guys heres the deal. I just started my new job working in manhattan and i've moved to near by Hoboken in New Jersey. My clients are primarily in the city or in the near by area; NJ, Westchester etc.

I have one parking spot at my disposal. I have a beater now, but after doing some commuting in it this week, i realize i want something better to spend my mornings/evenings driving around.

The mustang has been sitting at my parents house. Basically the only time it's driven is if i go home for the weekend, and it will be sitting for all of the winter soon for obvious reasons.

I'm not really in the position in my life to buy a nicer DD and still own the mustang. Plus it doesn't make sense to own a car that i will almost never drive. It really makes no sense to have the nicer of the two cars i own be the one that never gets driven

The problem is that im having a really hard time allowing myself to put it up for sale. I've never been so attached to a car before, but i get upset everytime i think about selling it. I've spent a lot of time and money on it and it has been my DD for the last two summers/springs.

Anybody have any experience with this type of situation? Advice?

Yea this is the dilemia i have.

The parking spot i have in jersey is in a parking garage so i'm not really worried about it getting messed up. But my girlfriend and i are more or less sharing the car and she can't drive the mustang, nor do i want her driving it. So it really can't be the car we have there. I could pay for another parking spot, but if i'm not really going to drive it, i don't want to do that.

As for a new DD, i don't plan on driving it in the city at all. Its basically there if i have to go somewhere in Jersey or in NY that is outside of the city.

I suppose i should crunch some numbers and see if maybe by next spring i can afford to upgrade the DD while keeping the mustang.
