Getting Another Triumph?

So the other night, Lady Luck suggested that we take the Vespa ET4 as well as the Vespa GTS over to Phoenix International Motorsports and trade them both in towards a Triumph Bonneville.

And I can't come up with a good reason for not doing it, apart from the cash difference setting us back in the plan to get her a newer car. Of course, setting us back from getting the car could be a good enough reason. Maybe P.I.M. has a used Bonneville that we could do a straight-across trade for.

Hm.
