Inverter welders

You are wrong, as always.

Yes.

Nope.

Hardly anyone scraps their current car when it needs a clutch change.

The garage cost of a clutch change or dual mass flywheel on an 18 year old Mondeo is £1,000, you may get down to £800 if you're lucky.

I can assure you, you can sell the car 'as is' for more than than a car value with a working clutch less the cost of fitting.

Perhaps you were more familiar with UK car prices you wouldn't look so silly. Perhaps you also misunderstand the UK colloquial expression "scrap".

My 73 Golf never needed a new clutch in the 45 years I was using it and I only replaced that car because I stupidly did nothing about the known windscreen leak that produced a damp floor after heavy rain and eventually rusted out the floor and I couldn't be arsed to fix that.

That's not scrapping the car.

That's what it can seem like until you get used to it - often splashing on some PlusGas before you start, or applying heat before you round or break the fasteners will get the job done without drama. And when bolts break you have extraction methods - my favourite is the weld a nut on technique but you also have cobalt drill bits and screw extractors and the taps to clean up the threads afterwards, and helicoils if that doesn't work out.
