Ford or not...I'll give to you what I think, straight.
Save for the 'Maro. but first, I have a question...it's a GT trim (300hp)...and it's not "fast enough" to tide you over?
But seriously, it all depends now, I guess on what you want more - disregarding current speed - Do you want a
better handling car, with
more power, most likely a
better interior, and overall
more pleasing to the eye?
Or do you want a fast car that's nice to look at, but not very kind in the handling dpt. compared to it's speed...
Up to you. But if it was me - I'd totally save for the better car.
