Ok guys i need some help or advice....

I am in the process of selling/trading my Honda RC51 for a VFR

I have two people with VFR's who would like to trade and I'm not very familiar with the bikes yet.
so my question is which should i go with or is there a big difference between the two

1st: 2008 VFR the dark silver color. it has 20,000 miles on it and is stock except for a full exhaust that was put on, paint and body are in near perfect shape.

2nd: 2005 VFR the lighter silver color, has 18,000 miles, aftermarket bars(not risers but full bars) slip on exhaust, givi windshield, givi bags, after market seat. paint has few minor scratches.

both are up to date on maintenance with the valve jobs already being done.

will i see a difference between the two bikes as far a years are concerned or are they basically the same. and am i dumb to pass up the older bike with lots of extras for the 08 bc i like the dark silver over the light silver but would be ok either way?

please weigh in on this and thanks for the help
