On the Quality issue, how many M3 have you driven?? How you know
the qulity is inconsistent?? heard from friends or facts from which
report??
Just use yr brain dear, even the korean car factory is automated,
who give you the idea that BMW SA factory is mannual?? the word
"Africa"??
Brand conscious suckers?? Good point. If I let you have the choice,
you may have the Evo or the M3, totally free, which one will you
choose?? the one which combines luxury, drivability, speed and
control or just the car which can be mod for power??
My point is clear, in Spore we are unable to mod the car to what
japan or even malaysia can do. What is the point to stress on the
point that what mod you can do to the car??
Both Evo and M3 are great cars, IMHO there isn't any point to
degrade any of them. Why not take a change, see how many good
points you can find in M3??Anyway both cars is of different level,
how to compare an apple to an orange?? Those who buy M3 will not
touch Evo, same to the Evo buyer. 
If you think M3 is of low quality and cheap, what car r u driving??
I personally can't affort it , I think you really have a high
standard for cars. Maybe only those "made in japan" meets your
standard. 
Keep stepping on the M3 makes ppl feel that you are sour grape over
it, open yr mind and look further my friend.
