Traded the ND Miata I had for 4 years for a Z4 M40i. No regrets other than the increased costs.
The Miata had a fully tuned coilover setup, sway bars, tuned engine, etc. Was literally like driving a street legal go kart around but the downside of that is it was… like driving a street legal go kart around.
Just wanted something more comfortable but still fun. Z4 it was!
