Congrats Vicky. Excellent choice (vehicle and color) and VERY tempting write up. To avoid downshifting to 2nd gear at 40kph, you will have to watch the rpm. Take her out on the Highway for establishing faster connect with the machine and tell us your experience.

The Mfr says "The codes for the antitheft wheel locks and keys are generated with a computer system for virtually infinite variants". It may be true, but the pattern looks similar to that in your post. Why don't you check if your unlock tool fits other cars in showroom ? If it doesn't you are cool. If it fits, you better improvise on MSN1's suggestion.
