Not choosing any car but one stat that keeps getting highlighted is which car is best. Have run both myself and both are really good conversions, reliability and g/box issues sadly leave one car out of favour.
On the results front.....
MCS - 2 years old and 2 national a finals (not regular)
Vega - 3 Nationals old 1 National a Final 4 National B Finals!!!
Lets leave that too other peoples opinions on results!!!
Personally i hope Fabs gets it sorted as you can't beat competition..
