I've had both cars N15 and N16. The N16 was more reliable and comfy and felt more quality but the N15 is quicker, and better handling although not as well built and less resistant to tin worm. (All IMHO of course).

Thats why i went for a N16 and not a N15...If i was single with no kids then a N15 it might of been so not its just getting the little N16 a little quicker.
