Purchasing a used 2020 Rocket 3 GT - what to look out for?

If I was a non Triumph dealer, I would take it to a Triumph dealer to have it reset before I tried to sell it, especially a late model expensive bike like that. There are other dealers and other bikes, I'd pass.
Triumph dealer here in Chattanooga wants 30 mins labor to turn out that stupid light. I guess it takes his tech that long to take the seat off.
 
The service light comes on as an agravation factor to remind u to change your oil.. Unless its flashing, nothing to worry about.
I have a 2020, and only issue is the rear brake bleed from the factory...
