I've had an excellent experience with
my Mustang. It's been exceedingly
reliable and has required very little
maintenance. In 49,000 miles
and "check-ups" every 3 months, I've
only needed oil changes, tire rotations
and air filters.
On the down-side, it's obviously
terrible in snow and ice. However, the
traction control makes a huge
difference. I've never been stuck and
I've driven in a lot of snow living in
Northern Ohio and Michigan.
Make the basic model front-wheel
drive. If someone is going to buy a
V6, he/she probably doesn't care about
the rear-drive performance.
