so i just bought a touring car off a good friend of mine.....got a great deal. I have a couple questions though. It is an OFNA hyper gpx4. it is mint condition....and i couldnt beleive how good of shape it is in. but i was wondering how old these cars were...like generation wise? it looks fairly new like a couple or few years old.....just wondering. and also if anyone has one of these or has had one....any tricks or anything i should know about going wrong or trouble spots to watch for. this is my first touring car.... thanks anyone with any info..
