Advice required

I’ve had my 60 plate vrs for 11 years now. The engine replaced/ reconditioned at 26000. Miles.

Excellent condition outside and in but everything is going wrong now.

Recently replaced gearbox, door loop, but now supercharger is on its way out.

It has 150k miles on the click and I need to commute to work 500 miles a week!

Garage has had to take it apart to discover what the matter is.

Supercharger is 1200 from vw plus labour. Is it worth paying nearly 2k to fix it?

I have used my husband’s car atm for work but I don’t know what to do as I need to tell garage asap.

I know I will hate this car for having to spend so much on it but how should I say farewell to it?
