The '18 was a 430 gran coupe. There was nothing not to like about it but the engine, transmission, and control upgrades in the '21 are pretty dramatic. I also like the configurable digital dash in the '21 and safety features that weren't available just three years ago. And the difference in the lease is less than $20/mo. I got mine pre inflation. I got the Z4 pre inflation too. It's a made to order roadster that sells at MSRP but I was able to get custom color brake calipers not on the price list at no additional charge. Order to delivery was 7 weeks because the dealer had a production slot reserved with a place holder build order. We changed the build order to our specs three days before the last date of change. I got a ball cap thrown in too. The Z4 is probably the last car we'll buy but I'll keep leasing sedans every three years as long as I can drive.Curious--what didn't you like about the '18 3-Series?
My first car was an ‘84 Impulse! My friends and I called it the Mouse-Mobile. I learned to drive standard shift in that car.I bought an Isuzu Impulse (Piazza) in '83 or '84...and really liked it. Ran well, no problems. Traded it off for a Mitsubishi mini-truck after we got married. We've never owned a car or truck by an American maker...other than antiques.
