I was right in the middle of both options. I've had:
Four Holden Gemini's (a TX, a TC and two TE models, both the TE's were done up for drag use, the TX & TC were just buy, bodge and sell jobs with a crapload of thrashing inbetween), two Mitsubishi Sigma's (a 2.0L auto & 2.6L manual), two Toyota Cressidas (both MX83's, the 2nd became a JZX83), plus heaps of one off's such as a Mazda RX4, a Mazda 808 w/13B Peripheral Port, a Datsun 1200 with a 120thou overbored A12 motor, and my mother had three Holden Barina's (one 1991 Suzuki Swift/Cino based, the other two ['94 & '98] were Opel Corsa based).
So I put down 4-6 since the Gemini's were my babies when I was growing up as a teenager.
