I must admit I didn't realise the extras the car had when I bought it. The wheels and the airflow kit together really made it look good when I saw it, and have always liked the look of the Z4 anyway, I just don't get the use out of it. Unfortunately having only done 3.5K in 4 years, I have decided to sell it. Just put it on Car and Classic.com so fingers crossed.
Thanks for your comments though, I'll be sad to see it go
