top speed wise you'd hope the mk3 is faster
as mass dosent affect top end speed just how long it takes to get there, you would hope a mk3 golf is more airodynamic than a mk2 ( there must be a reason for it being so fugly )
so more power and less drag it should go faster eventualy ( provied your on a long boreing straight level road wihtout any corneres)
going downhill the mk3 has an unfair advantage as it ate all the pies
as allread coverd accseloration wise the mk3 is going to be crap as its heavyy unless you've lightend it LOTS or as they rot so well the rustworm may have done that for you.
