I am actually a Brit, from London, UK but living in Thailand right now
The most similar forum to this one from my home country is this:
http://www.pistonheads.com/gassing/
the scene is different in the UK, because of less tax sports car's that are out of reach for regular people in SE Asia are affordable, but the high cost of labor in a garage makes it hard to afford mod's unless you can do them yourself, so I would not modify my car's much back in my home country, just drive a nice almost stock car. My last car in the UK was an Audi TT. I have attached a pic, miss it!
Here things are different, I cannot afford a sports car but is cheaper to mod a regular car and turn it into something fun to drive and own which I am trying to do with my Lancer.
I like Zerotohundred because it is much more relevant to the Local scene in Thailand, and lots of Mitsu knowledge here, which I am thankful for, but unlike Thai forums its in English!
All your advice is appreciated!
cheers
