Cheapest place to buy 125/250 cc quad bikes with free delivery to spain?

Yahoo it.

google it. but since america is having problem with the exchange rate by it from somewhere in america then ship it to spain

have you thought to approach a toy shop in the third world countries?

No need to have delivery. In Spain there are at this moment in time only two quads which are legal to carry two people. I tried them both and the very best one by a country mile is the Kymco MXU 500. I'm used to riding my new in 2006 Harley 883 Sportster and I also have a Trike Shop Harley Trike but the Kymco is so very much better fun. As I spend about all my time here in Spain you would be better buying one over here in Spain and don't have the difficulty with registration etc. You can get a smaller sized Kymco but I really don't see the point of something without a bit of grunt. I bought my quad in a little town just south of Barcelona by the name of L'Aldea and the name of the dealership, where English is spoken by the owner, is Motos Salvado and there telephone number should you need it is 0034 977 450 177.
Take it easy, regards David.
