Lissa hit the nail right on the head. Buying a dirt bike is not as complicated as for instance launching the space shuttle.,and should be fun.
The profit margin on motocross bikes is very narrow,and the invoice does reflect what the dealer paid.Dealers get 'holdback' money for bikes they sell,but it isn't much.On really slow moving units they may get an additional incentive,but again,not much of one with off-road bikes.They also have to pay interest on the bikes every month they have it sitting there unsold.
The dealers service,attitude of the employees,and standing behind their products is more important to me than a few bucks.
If I wanted to pick a bad investment,I'd go for paying 5000 bucks for the CHANCE to make 500-800,and that would be if I sold what I invested in for list! Factor in having to pay interest on the 5000,because I borrowed the money for the investment,and it doesn't look too hot,does it?
A buyer isn't getting screwed even if they pay list for a bike,even when they're buying more than one bike.Sure,take advantage of a good price.but don't think paying list or close to it is getting hosed.
Do watch out for freight and set-up fees,I think anything more than a hundred is too much for a dirt bike.
Enjoy your new bikes.You did well,and is anything prettier than a new dirt bike? Doug
