in an unbiast opinion i would say......Get a NTC3 i have this car a wouldnt swap it for any other 1/10 scale around the car is very fast, looks good, and low maintanance except for the diffs the only thing i despise about this car is the fuel tank BUT i think the fuel tank has been changed for the new kits! also this car is unbelievably easy to work on! and many hopup parts are being made for them now GPM, K-Factory, Hardcore Titanium, and the associated of course.
DONT GET ANYTHING HPI you dont get anything for your money and the car are badly designed (im not trying to slag these car off these are just my views and opinions) also the engines are way slow!
GT4 looks are okay car but i think the parts for this car are expensive and the car is belt driven meaning if you want to use this car where there are stones you want to be prepared to do alot of belt changing and maintanance.
