Had my Mk4 escort done recently.

Dropped the car off stripped. Windows out, doors/bumpers/skirts off etc.
Had a new front wing fitted and a few other small jobs like having a standard boot modified to take the spoiler (studs instead of holes) few small dents removed, prep work on arches I had welded on.

Full exterior and shuts. Paid £2300

Other quotes I recived ranged from £2000 - £6000 however, none of them actually seemed that interested in doing the job so I took my money elsewhere.
