There are a couple of chaps on here who could possibly advise on the import, according to the 2009 register, that Greyhound was in Italy, so it`s a real globetrotter!
There are many variations on the bumper theme, from none at all, through standard to any number of fabrications, I quite like the Aceca-style tubes.
As you say, the Sussex car is at the top end of the pricerange, but that`s just a startpoint for negotiation, and I would certainly want to get underneath & check chassis/suspension before shaking hands, which could obviously be a tad awkward with the Texas car!

John Goose, the Greyhound registrar, as he will be able to give you much useful information, shame we are so far from you, as I was going to offer to let you come and have a poke around the oily bits....
