this dealer is using a standard data sheet most dealers use,as you said it has 18" wheels yet he is adveriting it with 19" wheels
This car comes with
19in x 8.5J 7 - Arm Double Spoke Design Alloy Wheels with 255/35 R19 Tyres and Locking Wheel Bolts
130 miles is a long way to go not knowing much about the car 1 thing to try and get from the dealer is the spec sticker, one is on page one of the handbook or service book and the other is in where the spare wheel is kept, ask if he would not mind emailing you a picture than we can tell exactly what the car left the factory with
