First off, not looking for any advice or new cars.... but the chaos is over.
After crunching some numbers and taking a look at our finances figured selling mine and driving hers would make the most sense (... and be the most boring).
Sold my IS today for exactly what I paid two years ago (but did put some money into it). The plan isn't to buy something new, but rather pay off what we both owed on our cars, drive her Accord for the next year or until we move out of downtown. Doing this means I'm putting like 5k in the bank and between payments and insurance frees up like $800/mo.... while we're saving for a house, it makes sense.
Thanks everyone in the past 5+ threads about me being scatter brained with cars.... I should be done for a while..... unless.....
