1) Check frame and engine numbers against the log book. While many Lambrettas could have had an engine change due to improving the performance, or broken casings etc, the correct details for buying an original machine are important.
If speed or originality are not important to you then this is not such a great problem, but certainly at least the frame number must match the log book. Check the area of the frame number itself, as certain Lambretta machines become rarer, unscrupulous characters out there have been known to 'ring' the top models. Ringing is giving a false identity to machine. Taking a Spanish built Serveta and turning it into an Italian numbered machine means you have not brought what you thought you had, the scooter is also illegal and could be confiscated and even crushed if found to be incorrect. This scooter was in a copy of Scootering magazine for sale at £1450.00, offered as an Italian import with LCGB certificate! Of course it is not an import from Italy, but from the Far East, we can tell this because of certain trims, badges and general bodges always seen from bad restorers in this part of the world (were not saying they are all the same, there are good shops also, as there is good and part in all parts of the world). While this particular scooter is genuine, it is a good example to use due to some bad bodges on the machine to try to show what to avoid.
