Well, I couldn't take it any longer. I grabbed this Invader and brought it home today.
I am believing the 455 miles on the odometer. Look at the pics of the track and suspension. The track still has the little "nubbins" on it, and the track clips are still shiny.
The suspension still looks nearly new...even the original hyfax. The bottoms of the skiis look almost new....the original wear bars probably.
The passenger hand grips are broken, and the fuel tank filler neck has a small crack....no big surprise, but everything else is in amazing condition....and it runs, and runs fairly well.
But, like mswyka's recent post about crank seals, I will definitely replace these, along with checking out dozens of other things.
Amazing survivor....
