I got away with keeping it when I added my Porsche 968 Sport to the stable. Then I added a Citroën DS21 Pallas EFi.If you can keep it as well as getting a granturismo I’d do that. Better than money in the bank at the moment!
I’ve managed to keep my busso Alfa as well as the Maserati so far (clue in the username!) although the wife is not best pleased, it has to be said..
