I’ll start with the Porsche 997, the 996 looked alright imo, but it looks “like a 90s Porsche”, the 997 made it look sleeker and more modern. Still looks good today.
As for cars that looked worse after a facelift? Maybe the facelifted 6th gen Camaro? The 6th gen looked great pre-facelift, but they did something weird with the headlights and now it looks so-so…
Mazda MX-5 Miata NB to NBFL. 👌 Especially on the inside, but the outside facelift is nice too.
I’ve never been a fan of the NB1. Looks too much like a 5th gen Civic and not in a good way.
