RCMart is quite an interesting model shop, unlike any model shop I've been to before. It's essentially just a big warehouse with a front desk. It feels a bit like shopping at a trade counter. If you are looking to get a teamc car I might be tempted to contact these guys and enquire about price
http://www.harmonymodel.com.hk/contact_us.php it's a bit of a shame that their website is not that great as the stock and service they offer is fantastic. I popped in yesterday and took a close look at the TR04 and was quite impressed, I also know they have TC02 in stock.
I don't know what in the line of spares for these cars they hold, you have to remember that buggy racing is not very big at the moment in HK, the most popular class is on road and because this is actually what is raced this is what the shops generally carry spares for.
It was noticable at last weekends race in HK that a lot of people were wearing new TeamC Racing t-shirts - looks like they are definately making an impact here.
I'll probably get my hands on a TC04 as soon as I can and will post some pics on the build here.
