Anonymike your description of the Millenia as a “superannuated dog” cracked me up LOL 
The girlfriend had one for about three years before the G35 and I really liked that car. Had zero problems with it and she got drunk with a girlfriend one Saturday afternoon and went to the Infiniti dealership and bought the G35 that day (salesman’s dream, right?). I then sold it privately for her and you would be surprised at the number of people that look for that car. It has a sub-market that really wants it. But it was last on my list anyway, to find a 2002 with low mileage would be almost impossible.
To answer your question, the title is in both of our names. I would find a private buyer if she demands to have her name taken off of it and dissolve her financial liability. I’d like to say that this wouldn’t be a problem for her since I put down the downpayment and make all payments, gas, service, etc., on the car, but I never know with her. That’s why this may not be just a hypothetical want-to, it may be a have-to.
And I do see your point about paying it off or paying the principle down with her name still on it. She could claim the car at some point, but that would be off-the-scale mean even for her. I doubt I would have enough left over after paying everything else I need to pay to pay it off completely (and therefore have the title signed over to me), but paying it down was another option. But I do see your point that she could just claim the car. I’ll keep that in mind.
As far as the Camry, I’d like a leather, sunroof, etc. sort of car, and, once you get that stuff on a Camry, you’re pushing close to the same price as a Lexus IS250 in the used market. I actually like a smaller car, and chose the Elantra over a Sonata. I would look at a 2008-2010 Sonata loaded too. But, again, thatnks for the input about the title. Every little bit helps.
