Good deal. Looked far and wide for a P3 package with 18" wheels in a service loaner. Only found one in black with 19" wheels at $53K+. My best deal was $428 with prepaid maintenance on 36/10k with $428 down on a P2. Tax rate of 7.25%. No MSD’s applied. Car had 4085 miles at $50630. Wife wanted nothing to do with no voice command when making calls and didn’t want black. Went with the BMW 330ix. Congrats.
