76 years old. I have 40 plus years on a two-wheeler but gave it up about 8 years ago when my balance was getting bad. I sure miss the riding. I still drive a lot and enjoy it. I'm seriously interested in a new RT. Mom rode with me all those years and misses going along too. Would I be foolish to buy a new Spyder? No idea how many years I have left to ride. Ideas? When the time comes are they hard to sell?
If you're concerned about the financial aspect of buying a new Spyder, Mike makes a very good point about looking for a well cared for & cheaper version from amongst the earlier models.... and don't worry too much about reliability, if they've been maintained well & serviced at least as often as the schedule calls for (even - or maybe
especially if that servicing was done by a concientious home spanner-spinner!

), there's a growing number of them out there that've passed 99,999 on their odometer & are still going strong!.

On your other point, don't let your balance (or lack there-of

) be an impediment, many Spyder Ryders have balance issues to some degree, some worse than others..... (amongst other things, a blast induced TBI
completely destroyed
my balance some decades ago! So I call my Spyder my
Hi-Speed Mobility Scooter! 
) & some have far more debilitating &/or intrusive issues to contend with, yet they do so willingly & capably - and really, all the rest comes down to how much enjoyment you'n yours will get out of it..... you should probably also note that after the initial 'settling in' period (cos it does take a bit of settling in &/or re-training 2-wheeler reactions & muscle memory) very few seem to regret buying a Spyder for very long! :thumbup: Besides, if the Wife is keen to enjoy riding again, there's really only one thing to say..... and that's
Happy Wife = Happy Life!

So Go On... DO IT! You Know You Want To! :yes:
