Looks a nice car - assuming it's the green GTI ??
I'd fix it up, gotta be cheaper than shelling out of a new motor, which could also have "issues" so you could be back to square one.
If ya like the GTi, keep it and spend a bit [more] dosh. I agree a decent part worn - £20, windscreen Halfords sometimes have these mobile repair guys in that resin repair them [just a thought??] Tax - can't get away from it, steering rods are dirt cheap and you could do them, and the exhaust - if its buggered totally, hunt one down on eBay or get a local garage to do a healthy welding job.
I'd keep it
