Three things I have noticed about owing a porsche are as follows,
First: the styling is timless. A 1997 looks as modern as 2009 mustang,
Secondly: How many others do you see when you drive down the road? (mustang like every 10th car). and
Lastly: I always seem to get more than a kiss goodnight after a first date
(but I attribute that to my skills)
But seriously, drive the nissan and see what you think. If you can survive
LAP (life after a porsche) then do it. Just make sure you have no regrets!!
