To be perfectly honest dude I think he's taking the piss with that figure - I don't really know how much welding costs these days; but its definitely not what i'd call major - feel free to come and have a gander yourself and go from there

Well when i bought it from Tony the clutch needed doing, so i did that and changed the gearbox oil & flywheel at the same time. With regards to mods i've only changed the rear lights, cleaned the bay up, and changed the sound system a bit. Other than that i've just performed regular maintenance and enjoyed the car.
