For body kits, find a good body and paint shop. For mods, use an auto electrician for the sparky stuff, a mechanic for the oily bits, and a body and paint shop for the rest. Or better still, teach yourself and save a fortune on the bits anyone with a bit of knowledge and tools can realistically do at home.
Don't forget to check with your insurer BEFORE you make any mods at all.
Kwik $hit struggle to fit tyres and exhausts properly, I dread to think what mess their monkeys would do with anything else.
I wouldn't recommend going to Kwik fit for modifications. Use somebody who actually specialises in what you want to do.
Kwik Fit only do standard work, no bespoke at all.
No and don't ever go to KF for anything.
Dont use Kwikfit for ANYTHING.
