And, best of all, you could probably fit your LBC in the trunk of the Riv. Growing up, a friend of mine's parents had a Toronado, so I've always had a soft spot for the '65 - '70 models.
I've also been partial to the second gen Rivieras '66 - '68. They are similar in styling to the Toronado, but use a conventional rear-wheel drive layout. Right now, they are not commanding the kind of prices that the 1st Gen Rivieras are, so you may be able to pick up one in decent condition at a fairly reasonable price.
There's so many really undervalued / underappreciated Detroit Iron from the early to mid sixties. The "Bubble Top" GM Coupes of '61 and '62 are really spectacular, '61 - '64 Continentals and the aforementioned Rivieras and Toronados.
