Can you get 4 adults comfortably in a 197?

nah Ive had 4 people in Mine Russ....no problem at all
obviously performance goes down, but it doesnt struggle!
 
No problem at all. Had four lads on a 200 odd mile trip and they said it was comfy. The two rear seat passengers slept all the way...
 
If you have someone of 6ft 4 in the front then wont be lots of legroom for the person sitting right behind him. but tbh shouldntbe an issue. I had 4 lads in my car everyweek at one point for five a side footy and was ok, nobody complained.

Only slight issue was the performance. My car struggled at low speeds to accelerate despite the exhaust sounding like it was really trying lol. But once the revs are up above 4k it was ok in mine
