Howard, just NO. You expect it on the GT because of the track first heritage. On the Jag it looks like you may be trying too hard. You may as well get a sunblind across the top of the windscreen saying Boyce and Marleen and a set of furry dice
If you want something to provide a little edge ?
Get the suspension lowered.
Remove the mid/back boxes and replace with 3" straight through.
Maybe a set of subtle alloys that are after market.
Get some of the chrome made black coat
Make it a slightly more wicked but stock looking.
(however this is only my taste and each to their own!)
