The bug prodrives are great but then I would think that.
Look at the end of the day I myself have never held a subaru for more then a year as I just like to change them. I have had 9 since 2002 and all where great cars. I currently own a JDM bug prodrive and can safely say its going no where for a long time. Bug prodivers on a 02 plate are selling around €6500 - €9500 depending on condition and this oneis on a 01 plate so she's price in the regain of a good one.
Get a mechanic that knows what he's looking at to look at it for you. Thats the only way you'll know that it good or not. Theres a good few lads on her that will have a look for you. But I defo would never look at the number of owners on these cars unless your not planning on holding her for long.
