Depends what verion it is.
V3 are now cheap as chips and probably not worth anything with the V4 now being the next in line at its price.
V4 used to be around $2,000ish fitted and tuned, now days you can pick plenty up 2nd hand around $6/700ish and just pay for fit and tune. The plug and plays are easier, no time wasting with fitting so cheaper.
V5 just released fitted and tuned I believe will set you back about $2,500ish (not 100% sure tho) but worth every single red cent. They are a huge step up in the market.
Congrats on the new car tho, used to see a hot silver NA hatch around Rocko a heap, looked really good!
