Opinion seems to differ on this subject on every forum, it seems to be debated over & over again. Funniest one i just read was someone saying you'd be better buying a 130 because all the 150's would have been thrashed and 130 drivers were all sensible haha
Suppose it depends what you want to do with the car ..i have have only done minimal mods on mine ..stage 1 remap, wheels , suspension & headlights so if i ever do sell it i will return it to standard.
