A 1 series hatch really isn’t on the cards!
This is nice, but he wants 25k for it, which is too much.

A nice apecification car, I am confused why someone would advertise at £27k and be willing to take £25k,,, why not advertise at £25.5k, you may get more interest?
I can see that car at £24k privately due to the spec..... £24.5k if you really want it?
One thing you may want to look into if buying a GTi privately, this one appears to be out of warranty, as it's not mentioned?
Quite a few, if not some of us.

Have an all in package with VW, 2 x services, 2 years warranty, 2 x mot and 2 year AA cover for between £25-30 a month depending on deal available. This could take some concern out of buying a car privately?
