Purchase decision?!

Hello together! As you have surely seen at my headline I am about to fulfill my long-standing dream of being a part of it! I have to buy a Z3 Coupe 2.8. The 3.0l is a bit too expensive for me at the moment and for my fav. the M Coupe….naja there is the insurance a bit too expensive for me! What experiences have you made with your Zetti 2.8l? Is it susceptible to repairs? I will probably buy it from private from therefore it is important to me to know what comes to me bz w kann! I would have in the moment 2 to choose from: 03/00 62,000 km silver/tanit red 17 inch radial style 15.800 Euro 07/99 60,000 km silver/black 17 inch radial style 15.900 Euro I have to look at the 99 still test drive or me more closely. But according to the seller it should be tipp. Is the older so the other…! I have already driven the 00 or looked at it. What really bothers me, the aluminium rims have quite scratched…. or the paint leaves off the aluminiums at the front. Otherwise it seems in a good condition. Is there any way to remove the curb scratchers yourself? I wanted to ask the experienced zetti drivers for advice. Would you be very grateful for helpful answers! Thx
