Can anyone tell me more regarding car modification rules around here?

Can the engine be transplanted to any size/type? or is it cc/vehicle/brand specific?

Gearbox swaps? legal? how about auto>manual?

lets say if it's ok, what are the typical labour charges for
1)whole car paintjob.
2)interior refurbishment
3)engine work/transplant(pounds per manhour)
4)average cost for an alignment?

No idea on costs i'm afraid.

Well, cost is always a problem isnt it?

btw, from your post below, you work in central london? which part?

I stay in camberwell, and study at the strand. Plan to buy my first car here, still quite clueless on the details.

I work in the City near Moorgate.

Me too

I drive up to Tower bridge every day.

S4 stays in the garage, I get a bus ti the station and then train in. :-/

You can do what ever you want providing it passes an MOT.

Your insurance will go through the roof and may require an Engineersa report on the work done.

dear lord....5k pounds to insure myself.

LOL

Most stuff is a per-hour cost. Find a good garage and you'll pay around ?20 an hour.

Interior - be more specific. I was just quoted ?750 to redo all the seats (front and back) in leather.

As mentioned -you can pretty much do whatever you want to your car as long as it passes an MOT.

And keep your headlights a decent color - they get pissed off if too bright or bue/purple.

Located near Manchester myself.
