Im in the process of looking for a wrx sti and I need some advice on which one to buy

Buy a 03/04 Modded WRX with high approx 70-80km
-ECU tunned
-Intercooler with piping
-rims/king springs
-about 200kw atw
-service history

Buy a dead stock 03/04 Sti with low km less the 50km

For about the same price or more.

I just enquiring would the modded one be reliable for at say 200kw or will need internal work for it.

Just enquiring due to this will be my first wrx.

I work away ,so that I will not be driving the wrx as a everyday vehicle
