Actually speedmonkey, the ratio is exactly 50/50 on some years, including 2002. I have a 2002 and most will agree that it is the best year model to grab if you have a choice. 2002 or 2003, arguably, have the best suspension set up (some say it gets softer as years go on), the best engine choice, the better options like glass window and wind deflector standard, also a few extras like component speakers in doors.
A lot of people will say there is a big difference between AP1 and AP2 power, but most of those are people who don't own one and most likely have never driven one. I would say that they are so similar that it would take a driver a long time before he noticed the difference between the two. The AP1 feels at 8k rpms like the AP2 feels at 7k rpms to put it simply. There is no way that .2 liters will make a huge difference like some might think. The AP2 engine only has about 9 more lb/ft of torque available than AP1. The same can nearly be said of hp.
As far as size issues go- I really can't complain. There is plenty of room for me. Of course, I weigh about 140 lbs. and my waist is smaller than 30 inches around... I am 6 ft tall, and can say that I never have headroom issues. I think the car is snug and fits the driver like a glove.
Bottom line: its a specialty car for a specialty person. If you are a large person, who wants a torquey V6 engine, lots of room and practicality, and a smooth and comfortable ride- STAY AWAY! If you like to be snug in your car, like tons of feedback from the road, like hearing your engine working, and like high revving and screaming 4 cylinders then get that 2002 as quickly as possible.
I think that any way you decide to go, you will be happy. Just don't get a Grand Prix White, and we'll be cool.
