MX5 project - talk some sense into me / what to pay??

[broken biscuit]

I have the possibility of picking up a cheap MX5 for the summer. Do I or don't I? I just can't seem to make up my mind either way.

I have found for sale privately a red N plate mx5 (says mx5 not eunos, however, it has the bolt on fog light so not 100%). It has done 101k, and has all the old MOTs present. It has been sat in a workshop for sale since before christmas, and has just got progressively dustier. It has a flat tyre, flat battery and no tax or MOT i could find in the history although the seller thinks it still has MOT for a few months.

Now the crunch - the price - £650 on the screen, but I'm not prepared to pay anything near it.

Is it worth taking a punt for £250 - £300 on it? A battery and MOT will cost me nearly £100, without any work required, then tax on top. Am I being stupid, and should I go for it? Or should I just buy one with MOT and tax?

Will I be able to sell it without losing on it if I was to sell towards the end of summer? What sort of price would you expect to pay for a N plate MX5 with 100k on clock and an MOT?

Afraid not - just had a quick poke about while i was getting my tyres changed. I know it's N reg, got 101k on clock, has all old MOTs and no tax / current MOT. No rot to arches, but a flat tyre and battery. Red and dusty. Tyre fitter was Polish so not alot of help to fid anything out other than it belongs to the wife of the landlord of his unit
