my original plan was to get a three wheeler from Pete Larsen, only to find he had stopped making them...
I was in that exact situation in 2017 so I did want I could do then and bought a M3W to scratch the itch.
When Kankel posted here that Pete's ACE #10 was for sale (forever grateful to Kankel for that!) I immediately contacted the seller and we came to an agreement within the hour.
When I told my wife that evening, her reaction was simply, "you're not keeping them both, right?" and the M3W was sold.
Of course, a couple years later, I then bought yet another ACE; Pete's #13, 'The ACE of Clubs' and I even got close to a third ACE a while ago.
By my count there are 8 ACEs in the US still. My advice is to keep your eye out and be ready, if that's what you really wanted.
Pete's new ACE f-6 is also doing well and the first run of six have all been sold, with f-6 #4 in build now.
