Hi and welcome from another E85 Z4 owner. Mine is a 2003 car bought 4 1/2 years ago on 16,500 miles and it has its issues as most do. Yours at 13 years old will be no exception. Im guessing youre from the USA?I'm new to the BMW family and just purchased a used 2007 Z-4 with 26000 miles. I'm coming out of a Vette I had for 10 years. I like to hold on to cars hope, I didn't make a mistake but seeing some issues already. Wish me luck I may need it.
