Re: Personal Opinion on the best modification done to a 172/182 Performance or Stylin
^wrong.
If you want it faster, buy a faster car.
Most of the mods mentioned so far are relatively minor and inexpensive. They will improve the car without leaving you bankrupt.
I like my turbo clio, and dont have any of the problems you are claiming I will like being bankrupt etc.
Some people dont want a faster other car, they specifically want a clio, I fall into that category myself for this particular car in fact.
Goes without saying though with any power upgrade you should make sure the brakes and handling are up to it.
I read the question as what is the best mod he can do, not what is a cheap mod or what mod should you do as the only mod, so I was just saying that the biggest transformation (ie "best") ive experienced in any of the many clios Ive owned or worked on for others, is boost.
So I dont see how that is "wrong" ?
