Sell or keep Rover 75 1.8T?

Hello dear car fans! I have the following “problem”: My Rover 75 1.8 T Celeste L from 2005 has a defective gearbox / camshaft and the repair will cost about 1.500 Euro. Now my partner thinks I should sell it because it is so old and again and again bigger repairs occurred. In the meantime it is since November, because I could not decide for a repair or sale so far (and wanted). Actually the plan was my “James” (yes, my car has I asked several suppliers what a treatment would cost and we advised ALL not to do so. The car would not be worth it, because there will soon be no spare parts, because it has no olditimer potential or qualities, because Jaguar would be better, because… My James is elegant, sleek and beautiful, but in the years. Is a preparation worth her money or I throw my money out of the F Does anyone know anyone who is familiar with the preparation of British cars and can advise me here? Thank you for your support! Dio
