Welcome aboard Kiwistu. Nice clean looking ride, with low mileage for the year. Should last you many years. Looks like your neighbour across the road has one too - I wonder, did this inspire you or is it just coincidence?
It took me a while too, but I eventually located my E53 with the same interior. The black leather with titanium trim looks awesome and doesn't seem to age the car.
Noted about this forum - a great bunch of members with many positive threads, not just complaints or problems. You'll learn heaps if you read through the FAQ's and How Too's.
