135i/1 Series decision help.

Hi everyone im in my final stretch on buying a car, my eyes were set on a M135i, and a new one being a little out of budget and the pre owned still being that little much. I want to know your guys opinion, scale down to a F20 125i, or a 135i coupe.

I've been offered a good 35i, 2013 19 000km R409 000 lots of extras, im just unsure if the shape change and the somewhat dated interior will bug me!

Help? what would you do?

thanks in advance.
