advice from a owner of 30 some odd Guzzis over the last 30 years. (modified to reflect current corp ownership)
1 find the model you like
2 acquaint yourself with the lemon law in your state
3 buy the new Guzzi you like
4 do not get attached to it
5 hold piaggio to the letter of your lemon law
do this no matter how much or how little you like your dealer or the bike. The new ones are the best stuff Guzzi has made, but if you get a problem child get rid of it early do not "work" with your dealer or/ and Piaggio to make it ok, just make them follow the letter of the law and fix it quickly and correctly. Piaggio will just drag their heels till they do not have to deal with it. so if you get one of the 8 out of 10 good ones be happy and enjoy it, if you get one of the 2 out of 10 bad ones that will never work right MAKE THEM BUY IT BACK EARLY WHILE YOU CAN. IT CAN NOT BE TWEAKED ENOUGH to make a good bike out of it.
For example the state of TN law says that during the warranty period the vehicle must not be unservicable for more than 30 days in the first year. so if you have an issue that makes it unserviceable leave it for them to fix, the 30 days is cumulative if Piaggio does not supply a part in 30 days invoke the lemon law and make them buy it back, simple as that, it may mean you have to be the dick in the situation but that is ok...go with it...chances are your new one will be one of the 8 out of 10 good ones.
It also means that you may just spend a lot of money on something you cannot enjoy for a while, but it will be faster to get the lemon law buy back than to try to make a friday bike work...and far cheaper
