Do you mean HK$2000 for the car only, or complete set ?
If for car only, AE T4 factory team car la, full option + Proline wheels, I saw one in kws around HK$1600.
If for complete DIY set, Team C is OK.
If for compete RTR, Slash 2WD.
星星 buggy/truck...for fun is OK but for durable + fast run, no way la...unless you buy TRF.
