I am now in my late 60's so some of these cars go back a long way. I haven't included the supercharged '49 MG TC and '56 Austin Healey that I used to compete with in classic car races some 40 years ago.....ahhh, the memories.
1. 1949 Singer roadster
2. 1951 MG Y sedan
3. 1963 Datsun Bluebird (bought new...it was cheap and was a terrible car).
4. 1966 Valiant, bought new.
5. 1972 Valiant Charger bought new and these are now worth up to $220,000.
I bought it new for about $4,300 and sold it 2 years later for around $2,700. Impossible to predict at the time how valuable these cars would become.
6. 1974 Toyota Celica bought new.
7. 1977 Toyota Cressida bought new.
8. 1990 Mitsubishi Magna bought new.
9. 1993 Toyota Paseo bought new.
10. 1981 Mitsubishi Colt auto (don't laugh, it was for the wife).
11. 1991 MR2 N/A
12. 1999 Nissan Pulsar bought new (my daughter now has this car).
13. 1995 MR2 N/A Bathurst.
14. 1997 MR2 N/A GT (bought in 1999 and sold Feb. 2010).
15. 2008 Toyota Aurion, current family car.
16. 1999 Mazda MX5, current toy.
The most reliable and bulletproof car out of all these (apart from the last MR2 of course) is the 1999 Nissan Pulsar. It now has over 230,000 km. on it and has never missed a beat. It still does not use a drop of oil or water. I think regular and thorough servicing is the key.
