Value question 155

Hello I should have a value estimate of you Alfisti. Here in the village someone sells his 155 DTM edition. He says it is one of 500 pieces and he has the DTM glued. The car has run a little over 150tkm. Condition is quite good, but he has a slight tail damage. I’ve already looked at it, is really nothing wild and easy to repair. But there it has to be repainted at the rear. Is there still to buy the glue again? Because it has to be new at the back. Greeting Thoma s
