Put a tester add on Craigslist Dallas and see if you get any nibbles.
Don't know about Dallas but around here rural mail delivery people drive their own cars, a fuel efficient RHD car does have a certain market.
Not sure how reliable car you can get for $1500, but look at like you are with bringing your own car over, you'll loose $1500 in shipping cost, buy a $7000 Mirage drive it for 6 months and sell it for $5500. Cost same amount of money.
