How much should i offer him?
What kind of power should i expect?
Any other comments would be nice.
Sorry for the questions i'm new to the world of japanese cars :disappoin

that thing sounds nice i'm not fan of that kit but if you like it then its all good.
should be making like 200hp
dump the 17s they'll slow it down.
It sounds nice it depends what crxs go for around you what to offer where are you i'm sure someone can help you out.

thats a nice peice of work, but id say around 5-6000 for that car.
