fords inevitably rot quicker than other cars mate
my escort was polished waxed sealed frequently and the back arches on all 3 I had went to sh1t.
I'd keep the clio purely because I now think that fords are inferior. this is just my opinion of course.
and as has been stated above, the ford will drop like a stone in value whereas, your ph1 really shouldn't drop much more.
as someone said above tho:
stuff both. get a trophy.
