the zed is a heavy car, and the more you push it the more it will become apparent. it is in its essence a GT cruise and not an out and out sports car. it will eat the miles on a long drive with ease; have loads of trque for overtaking without needing to drop a cog.
if you want to run the zed on the track you'll need to upgrade the discs and padsstiffen up the suspension; tighten the chassis slightly.
and if your into modding and expect to get big gains from tuning and mods; again the zed will disappoint, filters, exhausts etc will have very little impact. unless you go FI then you need deep pockets.
the Zed is very capable but find the right example; plenty to choose from so very much a buyers market and not a sellers market.
