Citroen AX GT, are they worth anything much nowadays?

I've stumbled across a red one for sale cheaply. All paperwork pretty much from new after 4 owners, 98,000 miles and other than faded red paint, almost pink in places now, it's in good order. Clearly not a fast car but light at around 900 kgs i believe and 'lively' shall we say.
£700 seems good for a car with 11 months' ticket? Quite fancy it as a bit of a novelty and they are certainly rare as he's teeth now. F reg, 1989.

I have agreed to buy it next week. Tiny bit of rust on the door bottoms and i noticed it has a k and n circular filter rather than an air box but is stock otherwise. Wheels were refurbished a little while ago and look nice. £700 seems good.
