It really depends on a few things.
It is, unfortunately, a Standard car (but so are 800 others).
It's the only Australian made Ford in the game since the two FPV's got left out of GT5 (I'm still pee'd off over this

).
Almost any Aussie/Kiwi playing GT5 want it if they don't already have it (I get asked for it at least once everytime I take it online). It might be worth trading for something MUCH more expensive if you look at it that way.
It is comparable to DTM/JGTC. I have a lot of fun with it in Touring Car Only rooms. You don't see it much so I spend probably 80% of online with this one car.
I visit the UCD ALL THE TIME and the first time I saw it I didn't have the levels/credits. Second time I grabbed it. I haven't seen it again in over a month.
I'm a little biased, being an Aussie, but I hope that helps.
You could always give it some test drives then go back to the backup save.
