I don't think that Mk2 is worth £1500 (the price advertised). The leather seats look tired and you'll want to tidy it up.
If it was a GTI, even an 8v, I'd say it was worth it, but it is only a 1.6 driver. So it'll be a bit of a step down (performance wise) and if you sold the Mk2 later, you probably wouldn't make your money back.
But it's up to you.
