But i do agree that some cars are wider than others but only by
abit. I am not too sure about the Saab's width...
The best way to know if you might have trouble parking is to try it
when you test drive, all your queries on what you can do and where
you might have difficulties should be address and test out
then.
Saying that, the ability to park or not should not be hindering
your decision unless you really can't see or gauge.
Everyone needs time getting use to a new car, as each car's
handling is different, even for parking.
After sometime, when you have gotten use to the car, you will know
by heart how big the car is, what can or cannot be done and thus
your driving/ parking will improve accordingly. The "difficulties"
that you experienced earlier will deminish and would no longer
cause you concern.
