I'm currently looking to get back into a C63 having previously gone through an edition 125, a C63S and currently an M3. The BM is a lovely car but just doesn't compare to the C63 imo. Focussing specifically on a 507 edition, I'm learning they're few and far between with only a handful on the market. The good ones are snapped up quickly too. There's a lovely one sitting with an independent dealer with MB warranty running til end of the year. I know that MB dealers give 2 years warranty on used AMG but is it really a must have? I've heard the used warranties are pretty limiting and wouldn't cover big ticket items anyway. I guess I'm just hesitant spending so much money outside of the main dealer network.
