Welcome to the site, nice start in the vw family. Apparently silver is pretty unusual colour for the mk2, so I understand anyway. There's a whole thread on it in the mk2 section.
Skinny bumpers are the "in" thing at the mo' but ultimately personal pref. Easy enough job to swap but depends what you want.
As for wider tyres on the back, are they really wider? or are they not just stepped offsets? Have these on my BCWs. 15x8 all round but deeper dish on the back. Check the side walls of the tyres to confirm if they are wearing the same width of tyre or not.
The only thing that'd theoretically be wrong with wider tyres on the back of a fwd would cause understeer when pushing on as the front tyres would break traction before the skinnier fronts and as rears are only really there to stop the back end dragging along the ground.
But like I say I don't think they are actually wider at the back, just appear that way as they have a deeper dish out back and the person who made the original comment perhaps doesn't know his earhole from his @rsehole...
Oh and the Azevs are horrid, you should give them to me to avoid any further embarrasment
