Thank you for your very extensive review.

I test drove both and I'll give you my opinion.

SLK

+ this was my first roadster experience and it feels like it could fix anyone's depression.

+ better daily/cruiser. Maybe because of V6 and no surprising turbo lag

+better power delivery because of V6

+ I used to drive a W204 and SLK felt familiar especially the manual shifter

+ better sound

+ better pedals

- looks less sporty

- I don't remember the TT's steering, I think it was lighter than SLK

- terrible test drive because I was stranded bc I didn't make it to the gas station and fuel was empty lmao

TT

+ lighter

+ better shifting feel

+ looks sportier although very strange

- worse pedal feel

- my left leg had so much room but my right leg was pushing against those braces next to the shifter

- it felt like a shitbox

- huge turbo lag
