Over 86 months , it comes to $430 per month ... Am I missing something ?
I don't know if you should include the opportunity cost of the 8% per year, since you won't have that gain unless you completely eliminate an expense and start investing that money. If you're leasing something else you'd have to add the 8% opportunity cost to your new annual lease payment.
The good side is that your old Q is almost done depreciating, the taxes are low, the insurance is lower, etc. The downside is that it's a 12 or 13 year old car. From an economic standpoint you're almost always better off with an older car. Factors you'll need to consider is the timing chain guide issue, age and condition of your transmission, prior maintenence, etc.
As far as having your 17 year old daughter drive the Q, you know best as to how responsible she is... I was hell on wheels with a Honda Civic wagon because I absolutely hated it. I was probably a better driver when I got a nicer car. I'd feel better with her learning on a $5K Q vs. a $40K one.
