Anyone ever encounter poseur cars on the road? They are so
nicely bodykitted with mean sounding exhaust systems, they can have
even seasoned car enthusiasts fooled. Personally, I have been
fooled by some impreza 1.6 TS....everything including the interior
was done up as per STI spec, only thing was the red brake
calipers.....not the golden colour normally found on STI...but
still I almost bought it until the fella floored the car. Engine
note rises NOWHERE as fast as an STI and no PSST or BOV leh. Of
course not fast also 
While I can appreciate the work and effort put into detailing a
car, I think drivers of 'replica' cars should not race other cars,
you will remove all doubt about the true credentials of your cars.

Today I had my first encounter with a poseur M3, yep it had quad
exhausts, M3 styled side sills, M3 badge, M3 styled bumpers,
skirts....anyway I was convinced it was an M3....and that bronze
yellow colour so unmistakedly M3! Driver revving engine....engine
note very nice, until lights went green, engine very loud....but
how come cannot even keep pace with me and a passat ABT
beside....we have not even floored our pedals...just a brief
step-off
Initially,
I did not even press the accelerator much as M3 is way above my
league (no use to challenge) but the pseudo M3 was so sluggish, it
was HARD not to leave him behind.
Actually, immediately I knew the car was a dud....have seen how
fast a M3 can really go. Think the car was a nicely done up 318
CI....not even a 320CI as a 320 definitely has stronger
performance.
