There's no such thing as a cheap porsche.
A simple widget, if it was for a ford etc etc, would cost £1, for a Porsche it's £20.....and you'll need 6 of them........+ the fitting kit, new gaskets etc etc..! You'll have to drop the engine out.....and while you've got it out you might as well do..................

Before you know it, with labour and vat, a simple job has cost £3000...!
If you need body work, kidney bowls etc, on air cooled cars you're looking at considerable expense......🤷🏻‍♂️😱

I know all this to be a fact because I've bought a couple of 'cheap' Porsches...!

A cheap Morgan is a far better proposition.......!😆
