Welcome buddy I would do my level best to see the bike and complete the purchase in person. That way both parties are protected. Tomorrow you can't complain about the bike and he can't run away with your dosh. If this is the bike you really want then the time spent getting there will be worth it providing the seller has been absolutely honest about everything I once did a 1,400 miles round trip to buy a bike . Other than tiredness, the sale was completed in good terms and I was happy Good luck buddy
