Please go and buy a classic car.
Your skills and patience are excellent. I only got through the first page.
Please buy something worth restoring. But each to their own.
This may sound harsh, it's not meant that way.
To much effort on a rotting astra, for me.
But fair play.
Plus one for that - if this is practice you are ready for the real thing. I did something similar 20 years ago with a m2 Astra, days of work, paint job, got £700 for it.
Good work, bad choice of car.
Cos most rusted to bits and so few left. They were really good cars, rusting apart. They also hid the rust very well (ie they rusted fron the knside out).Scary thing is, nowadays folk are paying funny money for mk2 Astras.
Stick with it, refining your skills. Just try and find something worth rescuing and hide it away until it’s worth doing. It seems anything worth having just now has gone expensive.
