Buy an older Volvo -- before the Ford acquisition -- as countless
others have said. I would recommend a 1993-1995 940 Turbo, either in
sedan or wagon shape (depending on your preference). In my opinion,
they are the last of the "classic" Volvos. Don't get me wrong,
though...the Ford Volvos aren't bad cars by any means, they simply
aren't what they used to be.

Either way, buy that 1993-1995 940 Turbo (cost should be nothing more
than $7,000; I don't know about prices in Texas but here in Maryland a
good one runs about $5,000-9,000) and then put the rest of that $15,000
in a savings account for any repairs that MAY come up. You'll be in
good shape!
