Z4 Sdrive28i feedbacks?
Hi,
I'm am considering getting another Z4...will be my third. I like to have better gas mileage since it's a daily driver so the Sdrive28i seems to be lighter close to my old Z4MR and better balanced than the 35i(s).
Besides the HPFP and the power brake issues I research...are there any other issues with the Z4 E89 platform and more specifically the Sdrive28i 4 cylinder engines? Appreciate more information. Thank you!
