Tiff, some questions for you.

Is the car in the way?
Is the car paid for and not costing you money in repayments?
Is the car high maintenance and requires constand work/money to keep it on the road?
Do you enjoy driving the car when you do?
Is the only issue with the car that you don't drive it that often?

Sit back and look at the mand answer them to yourself. If your only reason is that you don't use it then fooking use it!!! It's only you that can rectify that.
