Ok, here comes....
I personally don´t like spoilers/wings/lexus taillights etc. I just don´t like making a mess of otherwise good looking bodywork....
I don´t like any of the previous even on a Jap car. I dislike all the japanese automobiles no matter what Scoobys or Evos they are. I find them just as interesting as Tamagotchis or Pokémon...Mainly because I don´t like corrosion, poor handling and plastic interior parts...and the toy-car looks of them..
However I find some improvements on a 406 very necessary myself...a) 15" or even 16" inch wheels look ridiculously small on a car that size ( and I otherwise do keep the 6 the best looking Peugeot ever made alongside with 205 gti, 206 and 605 facelift, so I think it´s worth the effort and lost of money if it´s anything more than just a workhorse to it´s owner..) b) lowering ( for one because of the soft suspension and for second because the empty space in the wheel arch looks stupidstupidstupid...
Otherwise the car looks best in its original shape
Here´s one for my taste, on a danish Peugeot forum....Other fine looking vehicles too in there...

And for Geordieboy.....the 18" wheels without the lowering don´t look that "straight" either...
Yet all in all everyone should have the right to do whatever the f*ck they like with their cars...
