Going to look at a bike Sunday

LOL

Not trying to argue but...

You left out maintainence. Oil changes, tires, batteries, etc. Those will make up the difference really quickly. Especially if you ride a lot.

He also left out the initial cost of the bike.

That's like people who trade their paid off car for a new one that gets good gas mileage. Yeah, it gets better gas mileage, but you can buy a lot of gas for your old car with the same $18k.
