well really the only hard part is wire-ing up the lume
all the putting in bits are generally fitting shit, just doing up nuts and bolts if u are fairly handy with a spanner i don't see why not you don't give it a go
it will cost alot more probably up wards of 800 - 1k for a mercanic
and thats the value of the car just labour
if you do a chunk ur self u can save a fair ammout
