What are the popular shops or the shops you know in Japan that is selling used performance parts,used engines, brand new performance parts and used cars?
Better google. Else Some folks would say you need/want 'spoon feeding' in this forum.
On the other note. This is a Malaysia site. I think it will hard for us to know where the shops are in Japan. But no harm trying.
My answer to you would be..I dont know. Dont know bout others though. Cheers.
For most of us, Sundays would mean staying under the covers for extended sleep mileage. Waking up late would be the best tonic after a night of partying, plus being the perfect day to get some shut eye before the arrival of Monday blues.
