Old Timer
People come in different sizes, and so do Can Am products. When buying a Spyder you must like the seating arrangement before making the final decision. If you like riding 2-up or riding single, you or both must be comfortable. As of 2019 your options were RT or F-3, but now the new 2020+ RT or RTL comes into play. The late models have more seating room, especially riding 2-up.
The 2019 you have your eye on sounds to be an excellent machine, but realize that the warrantee has run out, and the OEM tires are already 4 years old, and it is considered an early model machine now.
To me that machine would be worth less than $20K. I love the room and the ride of a 2020+ RTL.
Don't buy until you have ridden a 2020+ machine first! The difference in price would be worth the ride.
JMHO, give or take 2 cents, Bill
