2007 BMW Z4 Convertible 3.0i 2dr Convertible (3.0L 6cyl 6M)
Simply, a blast. Migrated from  535i
 2007 Z-4, Florida home. Avoid the bigger engine version since it comes only with the sport suspension which is a bit stiff. Test drive on less than perfect roads. Handling suspension terrific given mine was not the sport suspension. Paddle shifters. Decent mileage. Requires 91 octane for max performance. I gas up every 1/2 tank full, rotating between 93 premium and 87 regular. Get 24-25 mpg mixed city, country. Exterior finish exceptional. Abandoned run-flat tires. New set upon CPO purchase trash after 17,500. Switched the Michelin Pilot Sport A-S 3, std. replacement size 225/45/17. Less road noise, better handling. Also, so far 15,000 miles later, no road wobbling characteristic of many run-flats. Wobble symptom: (1) car jumping upon hitting routine concrete highway center seams and (2) on well worn country roads, tires tend to cause car to wobble sideways as tires run in routine tire track road surface depressions. Finally (at last, right?), car maintenance cost after warranty rather expensive, parts and labor. Bottom line, too bad BMW abandoned the Z line effective with 2018 model year.
